Performance Coatings Inc.
60 37th St NE # A Auburn, WA 98002 (253) 735-1919
Performance Coatings, Inc. offers a high heat ceramic coating that is capable of withstanding temperatures of 1300° F in Chromex™ and over 2000° F in Satin. In addition, it has very good chemical & corrosion resistance and possesses excellent thermal barrier characteristics, providing a dramatic reduction in radiated heat. This means reduced under-hood temperatures, accelerated exhaust gas velocity and a longer life expectancy for the entire exhaust system.
Unlike header wraps, ceramic coatings do not hold potentially damaging heat & moisture around the part. Rather, the surface temperatures are actually reduced, extending the life of the part. When cured, a very effective corrosion inhibiting film is formed that protects the part against oxidation and imparts excellent chemical resistance that further extends part life and enhances appearance.
