Sell activity surface treated silica powder

Description

Activity of silica powder is based on common crystalline silicon powder by a unique process uses silane and other materials on the silicon powder particle surface modification, thus altering the original properties of the surface, effectively improve the adhesive strength resin and silicon powder and interfaces hate water properties, thereby increasing the mechanical strength of cured products, elastic modulus, thermal aging resistance, weather resistance, more importantly, can greatly improve the mechanical and electrical products of partial pressure of free discharge phenomenon. Active silicon powder with resin, curing agent cross-linking reaction, but does not promote and block resin, curing agent for curing reaction, it will not affect the process of casting. Active Silica is widely used in high-voltage electrical appliances, casting, electronic materials, packaging and other industries.
