3. R&R - BEWARE OF COATED AUTOGLASS

 

Some automotive glass manufacturers are applying coatings on the interior of vehicle glass to provide heat & UV reduction.
Eg. 85% IR Reduction and almost 100% UV Reduction on EDTM Meter. 

 

Here's the irony, in Northeast Asia, these surfaces get scratched easily due to the coating on the surface, so some car dealerships provide a complimentary clear tint. However the day will come, when the driver wishes to replace the original film (due to scratches or for greater privacy), the coatings on the glass interior surface will be damaged due to the tint's adhesives during the removal.

 

It is like removing a tint on a Surface #4 of a dual-pane Low-E glass that is coated. Many tint shops are made to compensate on the glass replacement.

Damaged Surface of coated glass after tint removal:

Is Honda shipping US DOT compliant glass to US market that has that coating? I've removed film from late model Honda front windows and did not notice any damage.

Hi Sisqouc,

Glass with such surface coatings are only found on selected models.

A tell-tale sign would be a light yellowish-green tint on the original glass, using a piece of white paper as backdrop.

4. Visualizing Heat Reduction

 

Most window films can give consumers a high UV protection and various levels of privacy (VLT). Heat reduction becomes the primary factor for price differentiation. Many of our friends have a nice heat box to demonstrate the level of heat-reduction between various products. However, it is useful if we can present heat reduction to customers online and on marketing materials to encourage them to visit our tint shops:

 

Option 1: Thermal Imaging

A portable thermal imaging device costs about US$200.

Option 2: EDTM Heat Sheet
Heat Sheet is a temperature-sensitive card that changes color, when it encounters different temperature.

6. Comparing Heat Reduction

 

Generally speaking, these are the main wavelength in the electromagnetic spectrum that we are concerned with:

Ultraviolet: < 380-400 nm
Visible Light : 380-780nm

Infrared: >780nm

IR1000nm - Low Temperature, measured by most IR meters, illustrative example: air-conditioned room temperature
IR1400nm - Mid Temperature, illustrative example: morning sun.
IR1800nm - High Temperature, illustrative example: hot summer afternoon

TSER takes into consideration of the general protection against UV, VIS and IR.

 

 

 

If we are comparing products of different VLT and reflection,
TSER, SC and SHGC are good gauges because they take both VLT and IR reduction into consideration.
Eg. HP20 Charcoal is better than HP50 Charcoal tint.

Eg. Silver 35% architectural film offers better TSER, SC and SHGC than a HP50 Charcoal tint.

Assuming:
TSER of HP 50 is about 35%

TSER of HP 20 is about 53%
TSER of Silver 35 is about 63%

 

 

 

If we are comparing products of similar VLT and reflection,

Infrared measurement for 1400nm OR 1800nm are good gauges because they identify the product with higher solar protection, given the same VLT, eg. tinting regulation. 

Eg. 2-ply 35% HP dyed tint is better 1-ply 35% dyed tint from the same manufacturer

Eg. 35% ATO Ceramics tint is better than a 35% HP film. 

 

Assuming:
IR1800nm Reduction for 1ply Dyed 35 is about 13%

IR1800nm Reduction for HP 35 is about 38%

IR1800nm Reduction for 35% ATO Ceramics is about 90%

 

 

If we are comparing products of similar VLT and different reflection (different technologies),
Using both Infrared measurement for 1000 And 1800nm are good gauges because some technologies are meant to perform better at different temperatures.
Eg. 70% ATO Ceramics film has a weaker IR1000nm (low temperature) protection than darker 5% HP dyed tint but offers significantly higher infrared heat production at IR1800nm (higher temperature)

Assuming
IR1000nm for HP 5 is about 40% (HP 5 is better)

IR1000nm for 75% ATO Ceramics is about 30%
BUT
IR1800nm Reduction for HP 5 is about 45%
IR1800nm Reduction for 75% ATO Ceramics is about 90% (ATO is better)


Disclaimer: For simplicity reasons, a cheaper form of ceramics films - ATO is used in the above illustrations.

7. A Bad Tint is Worse than No Tint?

 

Is it true?
Probably... ... we risk compromising on driving safety if we give drivers a hazy tint or a single-ply adhesive-dyed tint that stains their vehicle interiors during tinting.

 

However, the cheapest automotive film of < 1 year fading durability will still reduce the impact from shattered glass during accidents and deters (slow-down) vehicle break-ins.

The cheapest automotive films in our industry offers 90-99% UV protection, offering some form of protection against the harmful UV rays to drivers who can least afford our films. 

In many ways, our products save lives.
Cheers!

Hi there Film Tack,

I just want to say that I enjoyed reading the information on this post. Every word of it. Thanks!

 

Particularly the Topic of 'UV 100'.

Lots of 'hype' words are used in our industry.. Carbon... IR... Nano Carbon... and so on...

You hit the nail on the head, and we can likely expect that the new 'hype' phrase will be UV100.

 

Like you stated, the window film supply market is tough. Any edge one can get is usually jumped upon, even if it is questionable.

 

I can see it now... "But madam, our competitor's product only cuts 99.9% of UV, and ours cuts 100%.

 

Once again, thank you for taking the time to put this information on Tintdude.

Take care, Cheers.
