SILRES® 604 is a flaked silicone resin that exhibits good compatibility with organic resins. It is primarily used as a pure binder in various applications. It is supplied as a solvent-free solid resin. One of the key applications of SILRES® 604 is as a base material for powder coatings. It is particularly suitable for heat-resistant formulations that can withstand temperatures up to 650 °C. Furthermore, when used in white formulations, SILRES® 604 can maintain its color stability up to temperatures as high as 270 °C without significant yellowing. The ability of SILRES® 604 to act as a pure binder and its high-temperature resistance make it a valuable component in the formulation of heat-resistant powder coatings.
