Now, let me take you through all the critical details of these polycarbonate sheets:

WeeTect Anti-scratch Polycarbonate Sheet

WeeTect Anti-scratch Polycarbonate Sheet comes with a high level of performance. It eliminates any possibility of scratches forming on the surface of the polycarbonate sheets.

This guarantees an optical class 1 performance.

Let’s face it:

It is a fact that polycarbonate sheet is not inherently scratch resistant. And, I know you do not wish to have a surface that looks like this:

Comparing surface with/without scratches

Comparing surface with/without scratches

Clearly, you can see that having scratches on the surface of a polycarbonate sheet can be annoying. In fact, it will render is basically useless.

With WeeTect Anti-scratch Polycarbonate Sheet, this will obviously be a thing of the past. WeeTect uses an ecofriendly anti-scratch coating (as you will see later) to protect all its products.

This product is popular with its brand name – WeeTect Scratch Resistant Polycarbonate Sheet (WASPCS). However, you can also refer to it as:

  • Hard coated polycarbonate sheet
  • Anti-scratch polycarbonate sheet
  • Scratch resistant Lexan

All these mean the same thing.

But that’s not all:

The good thing about this product is the ability to thermoform it to different shapes and sizes depending on your unique specific needs. That is, you can fabricate polycarbonate to different shapes and designs.

Owing to this unique property, you may also refer to such products as flexible scratch resistant polycarbonate sheets.

What’s more?

You have the freedom to fulfill your unique manufacturing needs with WeeTect Anti-scratch Polycarbonate Sheet.

I know you could be wondering how WeeTect has been able to achieve this:

Let me explain this as I explore the main substrates that add the anti-scratch property to the polycarbonate sheet.

Main Substrate on the WeeTect Scratch Resistant Polycarbonate Sheet

A number of quality tests in Foshan Laboratory clearly prove that this is a polycarbonate sheet with superior abrasion or scratch resistant properties.

Furthermore, the anti-scratch substrates are permanent and do not wash away easily.

It is for this reason that WeeTect Anti-scratch Polycarbonate Sheet is popular in many specialty applications. You will know more about this later in this section.

So, what does WeeTect use to achieve superior anti-scratch properties on polycarbonate sheets?

Silicon-based Anti-scratch Coating

WeeTect uses silicon based anti-scratch coating on all its scratch resistant polycarbonate sheets.

Depending on your unique application requirements, WeeTect will apply unique silicon-based anti-scratch compounds. It is a delicate process that involves controlling various process parameters for an effective anti-scratch coating.

For instance, preparing hydroxyl organofunctional silicone solutions involve a series of condensation and acid-catalyzed hydrolysis reactions.

In short, WeeTect has a range of silicon based anti-scratch coating that offers a perfect solution for its polycarbonate sheets.

But WeeTect does not end just by choosing appropriate silicon based anti-scratch coating.

Another fundamental issue that the company has addressed over the years is adopting an appropriate way to apply the anti-scratch coating.

WeeTect uses either flow coating or dip coating technologies. The two guarantee uniform and high quality coating on polycarbonate sheet.

Furthermore, we use either UV or thermo curing technologies to ensure the silicon-based compounds adhere to the surface.

What’s the bottom line here?

WeeTect Anti-scratch Polycarbonate Sheets feature silicon based anti-scratch coating.

Applications of WeeTect Anti-scratch Polycarbonate Sheet

Due to the numerous benefits of WeeTect Scratch Resistant Polycarbonate Sheet, it is popular in many applications. These include both domestic and industrial applications.

So, for the scope of this article, I will simply highlight the main applications of the WeeTect Anti-scratch Polycarbonate Sheet.

Some of these key applications include:

  • Face and eye protection equipment such as face shields, goggles, visors, etc.
  • Motorcycle windshield
  • Air craft windows and windshields
  • Signage and outdoor signs
  • Specialty glazing material

The truth is:

WeeTect Anti-scratch Polycarbonate Sheet has unlimited applications. In fact, this sheet is replacing glass in many applications.

As I mentioned earlier, its use in many applications is due to the numerous benefits it offers. Let’s have a quick overview of a few benefits of WeeTect Anti-scratch Polycarbonate Sheet.

Benefits of Anti-scratch Polycarbonate Sheet

When you opt for WeeTect Scratch Resistant Polycarbonate Sheets, you will enjoy the following key benefits:

Superior Anti-scratch Properties

Well, this is the main reason why you must apply anti-scratch coating on polycarbonate sheets. The good news is that, WeeTect uses silicon based anti-scratch coating that offer different degrees of performance.

They may range from >H1 to H9.

Basically, this makes them suitable for both general use and specialized applications.

Better Optical Properties

WeeTect invests in a range of coating technologies on its polycarbonate sheets to achieve optical class 1 properties.

When you have scratches on a polycarbonate surface, expect to have loss in light transmission. Basically, scratches on surfaces tend to interfere with the normal light transmission hence poor visibility.

You can Consolidate it with Other Technologies

Let’ be factual:

Eliminating scratches alone will not guarantee an optical class 1 surface. There are other environmental factors that will interfere with the light transmission, hence blurred vision.

These may include fog, UV, glare, etc. It is for this reason that WeeTect Anti-scratch Polycarbonate Sheet feature more than 1 coating technologies.

So far, we have the WeeTect Anti-fog Anti-scratch Polycarbonate Sheet. This polycarbonate sheet features both hydrophilic anti-fog coating and anti-scratch coating.

WeeTect Anti-scratch Polycarbonate Sheet is Cost Competitive

I know you’d wish to save some money by the end of it all. Well, here is a perfect solution for you.

WeeTect Anti-scratch Polycarbonate Sheet is cost competitive.

It offers excellent performance characteristics at affordable prices. This implies that you’ll save a significant amount of money.

In addition to these, the quality is yet another aspect that WeeTect give utmost priority.

Why?

Without proper mechanisms to control quality, you may not be guaranteed of optimal performance.

Let me take you through this:

WeeTect Anti-scratch Polycarbonate Sheet Quality Compliance

In Foshan Laboratory, WeeTec tests the following to ensure strict quality compliance and control:

  • Optical tests as per the ECE22.05 for diopter tests and ASTM D for haze tests
  • Mechanical tests are based on ISO 527, ANSI Z87.1/2010 and ISO 178
  • Physical property tests based on ISO 1183 and ANSI Z87.1/2010
  • Thermal property tests as per the ASTM D5470 and ISO 11357

Following these guidelines ensure WeeTect Anti-scratch Polycarbonate Sheets strict performance standards.

The polycarbonate sheet is available in different sizes depending on the specific needs of end users. You can choose from many dimensions, tints, VLT or gloss rate.

Here is a sample data sheet of WeeTect Anti-scratch Polycarbonate Sheet:

Apart from anti-scratch PC sheets, WeeTect also applies anti-fog coating. This is yet another critical technology in many accessories.

Let’s find out what’s unique about polycarbonate sheets with anti-fog technology.

In case you want to learn more about this product you can follow this link: The Complete Scratch Resistant Solution for Your Plastic Products.

WeeTect Anti-fog Polycarbonate Sheet

Ability to incorporate anti-fog coating on polycarbonate sheets is yet another significant milestone in this industry.

I am sure you’re aware that fog is annoying phenomenon that results in significant refraction and loss of light transmission.

As a result, you cannot see across a transparent surface clearly, which is quite risky.

Goggles made from polycarbonate sheet showing sections with & without anti-fog coating

Goggles made from polycarbonate sheet showing sections with & without anti-fog coating

Well, it was for this reason that WeeTect team decided to improve visibility on fogging polycarbonate sheet surfaces.

Of course, we have adopted an eco-friendly and cost effective mechanism to eliminate the fogging phenomenon.

So, what is an anti-fog polycarbonate sheet?

This is a polycarbonate sheet that has anti-fog coating on either one or two surfaces, depending on the nature of the application. The final polycarbonate sheet does not fog irrespective of the fluctuations in surrounding temperature and humidity.

WeeTect follows strict quality guidelines, thereby ensuring the final polycarbonate sheet conform to the EN166 and ECE 324 specifications.

Remember, you can apply this anti-fog coating on either injection molded components or flat polycarbonate sheets. All you need is an efficient coating technology – I will discuss that later.

Still, there is one fundamental question you could be asking:

What are the basic ingredients or chemical compounds in WeeTect Anti-fog Polycarbonate Sheet?

Main Compounds in WeeTect Anti-fog Polycarbonate Sheet

The choice of an anti-fog coating is fundamental here – why?

It will determine the efficiency with which the coating will prevent accumulation of water droplets on a surface.

WeeTect Anti-fog Polycarbonate Sheet features a hydrophilic anti-fog coating. This is an eco-friendly and reliable anti-fog coating.

Depending on your unique applications, WeeTect will choose a suitable hydrophilic anti-fog coating that meets your specific requirements.

The best part:

Our hydrophilic anti-fog coating is permanent – it can withstand several washings without losing its effectiveness.

As Kevin Lin, WeeTect Product Manager explains:

“We use polyester (PET) substrates alongside various hydrophilic additives that effectively bond on plastics to offer permanent anti-fog solution.”

This is good news that you can leverage on.

That aside – so how does hydrophilic anti-fog work?

Hydrophilic is a water loving ingredient. That is, it has high affinity for water.

Now, WeeTect relies on this property to eliminate fog on its anti-fog polycarbonate sheet.

I am sure you’re aware fogging is due to accumulation of tiny water droplets on a surface, which is due to fluctuations in humidity and temperature.

But that is not all:

The surface tension force is responsible for holding water particle together, thereby forming these tiny water droplets.

You can compare these two coatings

You can compare these two coatings

Hydrophilic anti-fog coating on WeeTect anti-fog Polycarbonate Sheets being a charge polarized water molecule, allows for hydrogen bonding.

During this process, it reduces the surface tension of water molecules hence water spreads into a very thin transparent film. As a result, there will be no tiny water droplets on the surface that could otherwise form fog.

As you can see, this process depends on molecular interaction – no chemical reactions.

Normally, the thin film allows maximum transmission of light with virtually no loss. You will see everything clearly.

Depending on the design of WeeTect Anti-fog Polycarbonate Sheet, the surface may act as a microscopic sponge. That is, it may have a cross linked polymer structure which uptakes this water.

Alternatively, when this water is too much, it will form a continuous film on the surface of the WeeTect Anti-fog Polycarbonate Sheet. Remember, this sheet is transparent and allows for maximum light transmission without any distortion.

Now, the thin film of water will flow downwards to the edge of the film. Of course, it will neither interfere with optical properties nor will you see it flow downwards.

This is a common phenomenon on WeeTect Anti-fog Polycarbonate Sheets on refrigerator doors.

Still, for the case of windshield, this thin film of water will evaporate as the vehicle moves.

Hydrophilic anti-fog coating

Hydrophilic anti-fog coating

In a nutshell:

WeeTect Anti-fog Polycarbonate Sheet feature hydrophilic anti-fog coating. This is an eco-friendly, reliable, efficient and permanent anti-fog coating.

Again, depending on your specific requirements, WeeTect use either flow coating or dip coating technology to apply hydrophilic ingredients on the surface. Furthermore, it uses thermo curing or UV curing to dry the coating.

What’s more?

WeeTect Polycarbonate Sheet may have anti-scratch coating and anti-fog coating.

That is, it may have anti-fog coating on one side and anti-scratch coating on the opposite side. However, all these will depend on the nature of the application at hand.

This implies that WeeTect Anti-fog Anti-scratch Polycarbonate Sheet (WAFASPCS) provides better optical properties. That is, it prevents fog and scratches at the same time.

Due to these properties, WeeTect Anti-fog Polycarbonate Sheet is popular for many applications. I will just list a few.

Applications of WeeTect Anti-fog Polycarbonate Sheet

Depending on your unique application requirements, you can thermoform or fabricate WeeTect Anti-fog Polycarbonate Sheets.

You can use it for:

  • Safety face shield
  • Polycarbonate lenses
  • Ski goggles
  • Motorcycle visors
  • Sport goggles
  • Industrial safety visors
  • Front and side windows of trucks, vehicles, forklifts, etc.
  • Cold storage applications such as refrigerators, dip freezers, etc.
  • Glazing applications and many more.

Applications of WeeTect Ant-fog Polycarbonate Sheet

The truth is that, WeeTect Anti-fog Polycarbonate Sheet offer unlimited opportunities in many areas.

With that in mind, let me take you through a quick overview of the various benefits of WeeTect Anti-fog Polycarbonate Sheets.

Benefits of WeeTect Anti-fog Polycarbonate Sheet

I will make it simple and straightforward for you to understand.

Our anti-fog polycarbonate sheet has a range of benefits hence, its popularity in many applications. These include:

  • Guarantees an optical class 1 surface; if you choose one with both anti-fog and anti-scratch properties, you don’t have to worry about possible obstructions due to fog or scratches.
  • Excellent impact resistance and dimension stability
  • Superior chemical resistance
  • Cost competitive

Basically, opting for our anti-fog polycarbonate sheet will obviously make your business profitable. Throughout the years, WeeTect has managed to achieve these through strict quality control.

That is exactly what I am going to discuss shortly.

WeeTect Anti-fog Polycarbonate Sheet

Quality control is an integral aspect at every stage in the anti-fog manufacturing process. This may range from:

  • Fabricating polycarbonate sheet
  • Formulation of anti-fog coating
  • Choosing appropriate coating and curing process

At WeeTect, we do all these depending on your specific needs.

Every time, we strive to have an ANSI Z87.1, EN166 and EN170 compliant anti-fog polycarbonate sheet. Therefore, WeeTect conducts a strict quality assessment and validation to ensure the product meets the right quality standards.

Remember, these products come in many options depending on your unique specific needs.

Apart from anti-fog polycarbonate sheet, at WeeTect, we have the UV resistant polycarbonate sheets too.

Also, I have a comprehensive guide to: Anti-fog Coating Guide and Anti-fog Solution eBook.

WeeTect UV Resistant Polycarbonate Sheet

Intrinsically, polycarbonate sheet has excellent physical and chemical properties.

However, ultraviolet radiation may render it useless.

I know you would not want to hear that, but that is the reality.

So, you only have one option – buy a polycarbonate sheet with UV protection substrates.

Don’t worry, I will explore more on this shortly.

The good news is:

Here at WeeTect, we offer a UV resistant polycarbonate sheet. This is the WeeTect UV Resistant Polycarbonate Sheet (WUVRPS).

UV resistant polycarbonate sheet

UV resistant polycarbonate sheet

With our UV 380 or UV400 resistant polycarbonate sheet, there is no need to worry about adverse effects of UV when using these sheets as glazing materials.

In most cases, we have UV protection on both sides of these polycarbonate sheets – a reason why WeeTect can confidently offer a 10-year warranty.

I know this may sound so complicated if you’re new to polycarbonate sheets. Anyway, let me explain:

Effects of UV on Polycarbonate Sheet

Our filters are based on years of research and experiments, focusing to reduce the effects of UV on polycarbonate sheets. Frankly, effects of ultraviolet radiations on polycarbonate sheets are quite devastating.

Under normal circumstances, polycarbonate sheet absorb some wavelength of the UV radiations. The effect of this process manifests itself as the yellowing of polycarbonate sheet after a period of time.

Remember, the aromatic rings and ester groups in the polycarbonate sheet tend to have high affinity for UV radiations. They are basically strong ultraviolet radiation absorbers.

Polycarbonate

Due to the UV radiation, the covalent bonds breakdown causing both:

  • Photo-oxidation; the 290 to 350nm favors this reaction.
  • Photo fries; it is the 310nm UV that trigger this reaction.

All these will severely affect the overall performance of polycarbonate sheet since they interfere with the chemical and physical properties.

It is for this reason that we recommend going for a UV resistant polycarbonate sheet.

Here is one secret that no other manufacturer will tell:

Do you know that the intensity of UV radiation varies from one region to another?

Well the amount of UV radiation the atmosphere can absorb varies with both the latitude and altitude.  This implies that, polycarbonate sheet may require different treatments depending on where you intend to use it.

Over the years, here at WeeTect, we have established that polycarbonate sheets tend to vulnerable more so to the UV within the range of 280 to 290 nm. This basically falls within the UVB wavelength range, which is 280 to 320 nm.

Polycarbonate sheet transmission spectrum

Polycarbonate sheet transmission spectrum

So, during the manufacturing process our UV coextruded polycarbonate sheets aim to filter all the UVB to prevent possible yellowing. It basically protects the polycarbonate from micro cracks.

Now, this leads us yet to another critical factor we consider at WeeTect:

UV Blocking Polycarbonate Sheet vs. Location

Earlier, in this section, I did mention that the intensity of UV radiation varies with latitude and altitude. All these parameters basically refer to the geographical location.

Many a times, OEM and distributors ask us this question:

Should I consider different UV blocking polycarbonate sheets for different locations?

Well, the answer to this may not be straightforward. However, I will give directions from my experience, supported by our research here in Foshan Laboratory.

When you install two polycarbonate sheets near the sea level and at the mountain just close to the Equator, the rate of degradation will be quite different.  The one at the mountain near the Equator will turn yellow much faster.

Reason:

This is due to the variation in the UVA and UVB in both places.

And by the way, why is this information important?

Whenever you’re buying a polycarbonate with a UV protection, you must insist that the manufacturer customizes it to your geographical location. This way, the UV blocking polycarbonate sheet will have special UV filters.

The good news:

Here at WeeTect, that is exactly what we do. Our WeeTect UV Resistant Polycarbonate Sheet is manufactured for different geographical locations.

This ensures maximum protection from UV radiations.

Applications of WeeTect UV Resistant Polycarbonate Sheet

Our co-extruded optical clear UV380 or UV400 resistant polycarbonate sheet is popular in many applications. This is because we can consolidate other coating technologies such as anti-fog, abrasion resistance, photochromic, anti-scratch, etc.

This leaves you with an optical class 1 surface that you can count on when it comes to safety. Some of the main applications include:

  • Aircraft windows
  • Dust covers
  • Windshields for motorcycles and vehicles
  • Outdoor signs and signage
  • Helmet visors
  • Face shields
  • Goggles, etc.

The best part:

https://youtu.be/fxOP-dXWKuc

You can use WeeTect UV Resistant Polycarbonate Sheet as a cut to size, thermoformed or fabricated material.

Therefore, this polycarbonate UV protection will always give you a peace of mind all the time, with many options at your disposal.

Once you choose our UV blocking polycarbonate sheet, you’ll obviously enjoy so many benefits.

Benefits of UV Blocking Polycarbonate Sheet

WeeTect UV blocking polycarbonate sheet will guarantee the following key benefits:

  • It filters all harmful UV radiations that could other cause yellowing of polycarbonate sheet. That is, it offers UV380 and UV400 protection.
  • Guarantees safety and superior optical properties; apart from filtering harmful UV radiations, you can add other coating technologies to ensure optical class 1 properties.
  • Ability to customize to specific location; WeeTect can provide UV blocking polycarbonate sheets optimized for specific geographical locations.
  • Cost competitive; when you compare WeeTect UV Resistant Polycarbonate Sheet to other related products, going for WeeTect’s is a better option.

In short, you have every reason to consider polycarbonate UV protection from WeeTect.

Quality Specifications of WeeTect UV Blocking Polycarbonate Sheet

It will be unfair to end this discussion on how polycarbonate blocks UV radiation without highlighting various quality specifications.

Well for WeeTect, we adhere to strict quality standards and procedures to ensure we have a high quality UV resistant polycarbonate sheet. Notably, our UV filters (UV380 and UV400) conform to the ASTM D 1003 standards.

You can review the data sheet below to learn more about our quality standards:

WeeTect Photochromic Polycarbonate Sheet

Upon request, WeeTect offers polycarbonate sheet with photochromic properties. This polycarbonate sheet automatically adjusts its tint depending on the intensity ultraviolet radiations.

Our WeeTect Photochromic Sheet & Film (WPSF) guarantees fast tinting and fading, depending on the ultraviolet radiation intensity. For instance, it takes less than 10 seconds to fade from 82.9% to about 11.2%.

Of course, this is due to the higher quality photochromic substrates that WeeTect uses on these polycarbonate sheets.

https://youtu.be/zrUScPbqT8k

Now, what’s so unique about WeeTect Photochromic Polycarbonate Sheet?

Main Photochromic Substrates on WeeTect Photochromic Polycarbonate Sheets

Well, it is important to choose high quality photochromic substrates for photochromic sheets. This way, fast tinting and fading will be a guarantee.

Also, I know there are many substrates that other manufacturers use in photochromic technology.

Here at WeeTect, we use eco-friendly photochromic substrates. Again, since WeeTect mainly focuses on polycarbonate sheets, we use carbon-based compounds.

Depending on your unique application requirements, WeeTect Photochromic Polycarbonate Sheets may have either naphthopyrans or indenonaphthopyrans. These compounds are safe and reliable.

Even though these carbon compounds may have different structures, the working principle still remains the same.

This is how they work:

The ultraviolet radiation breaks the bonds of these carbon-based photochromic compounds. As a result, they will have a completely different structure.

Photochromic is a reversible process

Photochromic is a reversible process

As this happens, the photochromic compounds will have weak bonds. As the molecules rearrange within the polycarbonate sheet, its species will begin to absorb light.

While absorbing light at stronger wavelength, the tinting process begins.

On removing the ultraviolet light, the carbon molecules will reverse to their initial structure. As a result, the polycarbonate sheet will retain its initial color.

So basically, whenever you see tinting on polycarbonate sheet that is basically a change in the structure of photochromic compounds.

Again, it is quite clear that this is a reversible process. That is, the surface tints in the presence of a certain threshold of ultraviolet light and fades in the absence of that light.

Having said that let me take you a step further to explore other aspects of WeeTect Photochromic Polycarbonate Sheet.

What’s Unique about WeeTect Photochromic Technology

Like most WeeTect Polycarbonate Sheets, you can cut to size, fabricate or use this sheet the way it is. Therefore, as a company, we must use an appropriate technology to ensure the polycarbonate sheet meets the dynamic needs in the industry.

This is why we use WeeTect Photochromic Technology (WPT).

Even with our new photochromic technology for polycarbonate sheet, we use either:

  • Photochromic coating; here we use special material to do the coating. So, expect a uniform and reliable photochromic polycarbonate sheet to your specific market needs.
  • Photochromic co-mold technology; it involves making photochromic polycarbonate sheet which is then co-injection molded to appropriate products.
Photochromic co-molding

Photochromic co-molding

In addition to this, WeeTect Photochromic Polycarbonate Sheet can also feature other coating technologies. These may include anti-fog, anti-scratch, anti-finger print or iridium coating, just to mention a few.

The entire process involves strict quality control to ensure uniform tinting of the surface.

In short WeeTect Photochromic Polycarbonate Sheet is a superior material with the super high VLT in the absence of ultraviolet radiations (e.g. in the house). On the other hand, it tints quickly on exposure to UV radiation.

Since you know how photochromic coating works and the main technologies, let’s now focus on its main applications.

Applications of WeeTect Photochromic Polycarbonate Sheets

Like other technologies, the situation is not different when it comes to the photochromic polycarbonate sheets. The main difference here is the functionality.

That is:

Here, the polycarbonate automatically tints and fades. Otherwise, all the other applications remain almost the same.

Photochromic goggles

Photochromic goggles

In most cases, you can use WeeTect Photochromic Polycarbonate Sheets to make:

  • Lenses and sunglasses
  • Safety eyewear such as goggles
  • Motorcycle helmet visors
  • Helmet visor inserts
  • Spectacles
  • Glazing panels
  • Augmented reality head up display, etc.

Clearly, there are hundreds of applications of photochromic polycarbonate sheets out there.

Depending on the unique applications for clients, WeeTect is always ready and willing to co-develop a photochromic polycarbonate sheet with special features. These may include adding military grade features such as ballistic features.

In short, it offers flexible and unlimited opportunities.

I am sure, you could be wondering about the main benefits you should expect from WeeTect Photochromic Sheet – here we go:

Main Benefits of WeeTect Photochromic Polycarbonate Sheet

By opting for WeeTect Photochromic Polycarbonate Sheet, you will enjoy the following key benefits:

  • Convenience

As I had mentioned earlier, photochromic polycarbonate sheets automatically tint and fade depending on the intensity of ultraviolet radiation.

This implies that, their tint will vary gradually depending on the UV intensity.

Therefore, there is no need of changing either goggle or visors with the varying UV conditions. Of course, I am referring to situations where you’ve opted for photochromic polycarbonate sheet to make these accessories.

  • Better UV Protection

At times, having a UV resistant polycarbonate sheet may not be enough. A photochromic polycarbonate sheet will help remove 100% of all harmful radiations.

As a result, you will not complain about any eye problems.

  • Offers flexibility in design

This is an important aspect, especially when designing safety accessories such as face shields or goggles.

Why do I say so?

You can consolidate photochromic with other coating technologies.

This implies that, WeeTect Photochromic Polycarbonate Sheet may have anti-scratch, anti-fog, hydrophobic or anti-glare coating. This way, you’ll have a multipurpose polycarbonate sheet.

In addition to all these, WeeTect Photochromic Polycarbonate Sheet is cost competitive. Therefore, you can also save a reasonable amount of money.

But, my analysis on WeeTect Photochromic Polycarbonate Sheet & Film does not end here.

Here is another critical aspect you must know:

Quality Control for WeeTect Photochromic Polycarbonate Sheet

As you will see in the data sheet, WeeTect follows strict manufacturing standards.

Here at WeeTect, we have adopted various quality testing standards for photochromic polycarbonate sheets. These include:

  • VLT before and after photochromic tinting, which must conform to the ASTM D 1003 standards
  • Time taken for full tint and fading conditions

For other quality testing standards, you can refer to the data below:

WeeTect Anti-glare Polycarbonate Sheet

At times, the impact of various light sources can greatly affect the beauty of various polycarbonate surfaces. This is even annoying if you cannot find a perfect way to eliminate unnecessary glare on surfaces.

It is for this reason that WeeTect has developed effective and reliable anti-glare polycarbonate sheet.

Generally, our anti-glare polycarbonate sheet reduces possible glare and reflection. As a result, sufficient amount of light passes through the polycarbonate sheet thereby improving vision quality.

To achieve this, we use high quality AR coating, which we apply on the surface of polycarbonate sheet.

Over the years, WeeTect has been investing in producing high quality anti-glare substrates that meet the dynamic market needs.

I am sure you’re beginning to wonder which kinds of compounds possess this property. I will explain:

Anti-glare Polycarbonate Sheets Substrates

Ideally, an anti-reflective coating is a dielectric material with the ability to alter the refractive index of polycarbonate sheet. The effectiveness of this process will depend on specific compounds of the substrates.

Some of the most common AR coating substrates include:

  • Magnesium Fluoride (MgF2); with just a single layer of this coating on polycarbonate sheet, expect it to reduce 4% to 12% of reflectance. It is a popular anti-glare substrate.
  • Zinc Sulfide; in case you want either low or high transmission substrate, this can be a perfect alternative.
  • Silicon Nitride; when it comes to solar cells, silicon nitride is a good AR coating.
  • Yttrium Floride; it is suitable for infrared region just above 5µm.

Honestly, there are a quite a number of anti-glare coatings for a range of applications.

Therefore, depending on your specific applications, you will get WeeTect Anti-glare Polycarbonate Sheet with the right coating. We allow for custom options.

Depending on your unique requirements, WeeTect can offer:

  • Single layer anti-reflection coating
  • Multi-layer anti-reflective coating
  • Absorbing AR coating
  • Gradient index AR coating
  • Circular polarizer

At WeeTect, we use an AR coating that eliminates all possible reflections from polycarbonate surfaces. By allowing light to pass through the surface, it improves vision.

In a nutshell, the anti-glare coating absorbs part of this light leaving you with an optical class 1 surface.

As we design the WeeTect Anti-glare Polycarbonate Sheets, we pay close attention to the anti-reflective thickness. At any given instance, we try to maintain the thickness of the coating to an odd number of quarter bandwidth ranges.

The idea here is to achieve an appropriate acoustic interference.

I know that may seem so complicated for newbies in the anti-glare polycarbonate sheet industry.

Don’t worry, we do all that formulations and calculations in our manufacturing plant. All you get by the end of it all is a high quality WeeTect Anti-glare Polycarbonate Sheet.

That’s not all.

Just in case you need assistance on this, WeeTect team is here to help – just contact us.

Now, how does WeeTect apply tint on polycarbonate sheet?

The complexity of the polycarbonate sheet tinting process will depend on the desired final finish of the surface.

One of the most popular processes is the immersion technique.

This process involves immersing polycarbonate material in a mixture of dye and pigment. It is this mixture blend that contains the impregnating solvent.

During this process, this solvent attacks the polycarbonate sheet. It then impregnates the pigment and dyes into the polycarbonate sheet.

By slowly withdrawing the polycarbonate sheet, a graded tint form on its surface.

It is this polycarbonate with graded tint that you can further fabricate or thermoform to form other products such as lenses, goggle, face shields and other products.

As you can see, this is more of the dip coating technology. Therefore, it is important to adopt a suitable curing technology.

Also, depending on the final finishing, you may adopt other polycarbonate tinting technologies.

Remember, this process is strictly controlled to ensure uniform tinting.

At every stage of the when we make WeeTect Tinted Polycarbonate Sheet, we focus on controlling the following:

  • Standard color

The color options depend on specific application requirements. They may range from blue, brown, opal, yellow, green-blue and many more.

  • Minimum bending

Normally, the bending radius will vary depending on the polycarbonate thickness. It is an essential aspect to consider, especially when you’re intending to fabricate polycarbonate sheet.

Other factors to consider at this stage soundproof specific gravity, standard width and length.

In short, at WeeTect, we do everything possible to ensure all tinted polycarbonate sheets meet the right quality standards.

Benefits of WeeTect Tinted Polycarbonate Sheets

Our tinted polycarbonate sheets have the following key benefits:

  • Easy to control light transmission and energy

By tinting polycarbonate sheets, we control the VLT. This is basically the process of controlling that amount of light that can pass through the polycarbonate sheet.

As you can see, tinted polycarbonate sheet offers some privacy. It is therefore a perfect choice for glazing applications.

  • Guarantees safety

By reducing light intensity and improving contrast, you can see everything clearly, more so where they make face shields and goggles.

It is therefore a perfect choice for making eyewear accessories.

  • Superior optical visibility

Tinted polycarbonate sheets improve contrast and visibility in foggy weather, especially for yellow and orange tints.

In addition these WeeTect Tinted Polycarbonate Sheets are also cost competitive compared to other products available in the market.

It is due to these that tinted polycarbonate sheets have become popular in many applications as you will see shortly.

WeeTect Flame Retardant Polycarbonate Sheet

I want to introduce you to yet another product – WeeTect Flame Retardant Polycarbonate Sheet (WFRPS). This is a clear flame retardant polycarbonate sheet that conforms to the UL94 V0.

I will explain more about the UL94 V0 standard later in this section.

Flame retardant polycarbonate sheet

Flame retardant polycarbonate sheet

Generally, polycarbonate sheets have superior chemical and physical properties. However, there is a need to ensure that it meets specific flame retardant standards.

This way, you can confidently recommend it for specialized applications in different industrial setups. I will have a quick overview of these applications later in this section too.

Like other WeeTect polycarbonate sheet products, it is an impact resistant material, which is transparent. However, you can also incorporate tint to achieve a suitable VLT.

Again, the whole idea of going for poly carbonate sheet does not revolve around flame retardant features. There is a lot more that you should consider.

The best part:

WeeTect can also include other technologies to improve the optical properties of this fire retardant polycarbonate sheet.  For example, it may have:

  • Hydrophilic anti-fog coating; it manipulates the molecular structure of water droplets, forming a very thin film hence, eliminating fogging.
  • Anti-scratch coating; this is a silicon based substrate that prevents the chances of scratches forming on polycarbonate sheet.
  • Tinting; it involves varying the VLT to suit specific needs of an application.
  • UV resistant properties; it eliminates all harmful ultraviolet radiations that cause yellowing on polycarbonate sheets.

Remember, these are not the only technologies. There are other coating technologies, alongside those that aim to improve the optical properties of polycarbonate sheets.

By choosing an appropriate coating for polycarbonate sheets, you will obviously have an optical class 1 surface.

Apart from that, let me take you to another vital aspect:

Why is UL94 V0 Important in Flame Retardant Polycarbonate Sheet

WeeTect is a market leader in formulating various coatings or technologies you can use on polycarbonate sheets. Therefore, the company adheres to strict quality control and conformity at all times.

It is for this reason that WeeTect Flame Retardant Polycarbonate Sheet is UL94 V0 rated. This implies that it is safe for most industrial and domestic applications.

I know you’re wondering what UL94 V0 is all about – I’ll explain.

UL94 V0

What is UL94 V0?

And, why is it important in polycarbonate sheets?

First, it is important to state that the UL94 V0 is an important safety standard in many industries. We use it to rate the flammability of materials.

It is a standard that was released by the Underwriters Laboratories.

Honestly, there are many UL standards however, for the scope of this section the focus will be on the UL94 V0.

The UL94 is a standard flammability testing procedure that is specifically for plastic materials. This is why you find some people referring to fire resistant polycarbonate sheets as UL94 V0 polycarbonate.

Furthermore, the “V0” simply refers to a vertical flame test. Remember, you can conduct the flame tests at 45° or alternatively in horizontal position.

Therefore, the “V0” is simply a classification designation. Again, this “V0” implies that once burning commences, it stops within 10 seconds.

What does that tell you?

WeeTect Flame Retardant Polycarbonate Sheet is almost incombustible or rarely ignites.

Honestly, achieveingUL94-V0 is quite difficult. It involves proper formulation of various chemical compounds to produce virtually incombustible polycarbonate sheet.

From this discussion, I know you can figure out the fire retardant performance of WeeTect polycarbonate sheet.

Having said that, so where can you use the UL94 V0 polycarbonate sheets?

Practical Applications of WeeTect Fire Retardant Polycarbonate Sheet

Depending on your unique applications, you can use WeeTect Fire Retardant Polycarbonate Sheet as a cut to size material. Alternatively, you can fabricate or thermoform these sheets.

Generally, I can recommend WeeTect Flame Retardant Polycarbonate Sheets for applications where flame can be catastrophic. By choosing flame retardant polycarbonate sheet, you can easily control the spread of fire.

Since you now know the main applications of flame retardant polycarbonate sheets, let’s have a quick overview of its main benefits.

Benefits of Flame Retardant Polycarbonate Sheet

When you opt for flame retardant polycarbonate sheets, you’ll enjoy the following main benefits:

  • In case of fire outbreak, you can easily contain it without causing much damage

Being a UL94 V0 rated material, there will be virtually no combustion or very minimal if any in case of fire. This makes it easy to control the spread of fire, especially in areas with highly flammable substances.

  • Superior optical properties

When you incorporate other technologies such as anti-fog, anti-scratch, UV resistant or photochromic, polycarbonate surface will guarantee optical class 1 properties.

With these coatings as options, you will not experience any fogging, glare, scratches or harmful UV radiations.

  • Strong and durable

Polycarbonate sheet is impact resistant and virtually unbreakable. Furthermore, with the UL94 V0 rating, you don’t have to worry about the polycarbonate sheet losing these properties in case of fire.
