KTA TATOR LABS
Because there is no known standard to test the water shed properties of automotive waxes and paint sealers, KTA developed and standardised a method which also tested the durability of the Glass Coat product.
The testing consisted of determining the range of which water shed from the surface of glass coat compared to uncoated panels and panels coated with four other automotive paint sealers. The water shed rate both before and following subjections to a pre-determined number of linear wash cycles with a sponge and a detergent/ water solution were compared in order to gauge the durability of the products applied to test panels against the combined effect of physical washing in chemical detergent.
After 5000 washes, Glass Coat exhibits little or no erosion.

An accelerated weather test was selected to assess Glass Coat's durability. A "Weatherometer" cabinet is the equipment of choice for such a test. It is understood within the automotive coatings industry that 500 hours in the cabinet is a reasonable approximation to 2 years of coastal weather.
At 750 hours the Glass Coat panels exhibited no reduction in water repellents.
At 1,000 hours, a clear difference between coated and uncoated sided was evident, and water repellent properties were still obtained. Exposure was continued to 1,500 where little reduction is evident.
These panels were then run to the 2,000 hour mark.
Glass Coat's Polysilazane coating is held together by silicon - oxygen (Si-o) bonds, which are unaffected by UV. Polysilazane strongly reacts with the hydroxide (O-h) groups on the surface of the paint to anchor (chemically bond) it in place at millions of separate points across the surface.
For this reason, a true Polysilazane product is expected to perform very well on an accelerated weather test.
Glass Coat was still intact after 7 years. All major brands tested failed within 2 years.
