Anti-yellowing additives are specially developed modified composite additives for high-temperature resistant powder coatings; this product is a specialized additive developed for high-temperature resistance purposes, capable of achieving high-temperature powder coating effects at 300-700 degrees, and demonstrates excellent high-temperature resistance in powder coating systems.
The coating formed after heating and cross-linking of the product has a fine surface, smooth and even; pencil hardness is 1H when the surface is undamaged; after prolonged high-temperature baking, it still maintains excellent adhesion and outstanding gloss retention; it does not decompose when stored long-term in powder coatings and does not affect the storage stability of the powder coatings.
