Polyphen Piston Top Gold Thermal Barrier was originally developed for top fuel drag racing engines. It reduces heat penetration on coated parts and can be used on any combustion chamber surface in any type of engine. It also evenly distributes heat, reduces hot spots, aids in flame travel and combustion, while reducing the amount of heat the incoming air/fuel mix absorbs, reducing the potential for detonation. 

This thermal barrier also sheds carbon, reduces carbon buildup, is solvent based, and cleans up with Acetone or similar. Requires oven curing at 300°F for 1 hour. Part #TL-PTG available in Quart & Gallon. For professional applicators only.
