VHT Flame Proof Coating SP118 Flat White Primer is the base coat for the three part multi high performance coating system. VHT Flame Proof Coating will extend the life of any surface exposed to extremely high temperatures. This unique coating is a matte finish, silicone ceramic base widely used by the automotive industry on exhaust systems, and the aerospace industry for jet engines, re-entry vehicles and other high temperature applications. VHT Flameproof Coating will withstand temperatures up to 2000 degrees Fahrenheit (1093 degrees Celsius) and is ideal for use on headers, exhaust systems, or wherever an extreme temperature coating is needed. VHT provides a multi high performance coating system for the ultimate protection and quality. The system of primer, paint and clear coat finish is applied with a curing process to insure top performance. VHT Flameproof coating only attains its unique properties after correct curing. Curing can be done on the vehicle or off the vehicle by using the following steps. ON the vehicle, paint must be completely dry, run engine at idle for 10 minutes, cool for 20 minutes, run at idle for 20 minutes, cool for 20 minutes, run at normal operating conditions for 30 minutes. OFF the vehicle, paint must be completely dry before curing, heat to 250 degrees for 30 minutes, cool for 30 minutes, heat to 400 degrees for 30 minutes, cool for 30 minutes, heat to 650 degrees for 30 minutes. (CAUTION: Do not exceed the temperature of the least heat tolerant component or the base metal.) Complete application and curing instructions are also printed on every can.
