PROSILANE™ SC-7910
Product Description
Di-tert-butoxydiacetoxysilane is an organosilane compound featuring two tert-butoxy groups and two acetoxy groups attached to a silicon atom. It is primarily used as a crosslinking agent in silicone and hybrid polymer systems, with high reactivity towards moisture and hydroxyl groups, enabling it to form strong bonds with inorganic and organic materials. It readily hydrolyzes upon contact with moisture. SC-7910 is used to take off the acetate type RTV 1 adhesion promoter, promote the caking property of aluminum and other metal base materials. SC-7910 usage level is about 0.3 to 0.5%.
