Dynasylan® 40 is a ethyl silicate with a silicon dioxide content of approximately 40 - 42 % upon complete hydrolysis. It is formed in the presence of water from tetraethyl silicate (Si[OEt]4) by partial hydrolysis of the ethoxy groups to hydroxyl groups and subsequent condensation with formation of siloxane bonds (SiOSi). Used in adhesives and sealants.
