The high-temperature resistance of powder coatings can be achieved through the use of special resins, pigments, additives, and antioxidants. Organosilicone resins, due to their higher bond energy and oxidative stability, are the preferred choice for the main resin in heat-resistant powder coatings. The selection of pigments and fillers is also critical; materials with high stability that can react with the resin should be chosen, such as mica powder and silica micro powder from the silicate family. Moreover, the addition of high-temperature resistant additives and a composite antioxidant system can effectively enhance the thermal stability and color fastness of powder coatings at high temperatures. Through the optimization of these formulations and processes, powder coatings can be applied to high-temperature environments, such as grill coatings and exhaust pipes.
