The 7650 Q2 Quartz Ceramic Coating is a glass like coating based on silanes. This coating can be applied by spray or by wiping but in all instances it has to be buffed after application.

After application the 7650 coating is exceptionally easy to buff. The resultant layer provides a deep gloss with high hydropho- bicity. The coating is neither paint, wax nor a sealant, and cannot flake off or be washed off. The coating forms a durable (“covalent”) bond with the paint, and it can only be removed by strong abrasive forces. The coating cannot be dissolved by standard chemicals which are commonly used in the auto sector.

As noted, the coating provides a long lasting, highly glossy ap- pearance, but as with all surfaces abrasion will eventually impact on the coating. The useful life of the coating will depend on the amount of abrasion that the surface is subjected to but re-application is a simple procedure.

We use the familiar “pencil hardness” to describe the hardness of a layer. The measuring range is between 6B (smoothest) and 9H (hardest). The Auto and Aerospace 9H Ceramics Coating achieves a hardness grade of *8H (drying at indoor temperature) up to 9H (heat drying).

*The hardness of a coating is measured when the coating is applied to a metal test bed. If the coating is applied to a soft painted surface the hardness of the coating will remain constant but the underlying soft painted surface and the coating can be distorted if point loading pressure is applied.
