PROSILANE™ SC-7950

Product Description

Ethyltriacetoxysilane is a silane compound featuring one ethyl group and three acetoxy groups attached to a silicon atom. It is widely used as a crosslinking agent and coupling agent, particularly in silicone and hybrid polymer formulations. Its ability to hydrolyze in the presence of water makes it effective for creating strong, durable bonds between organic and inorganic surfaces.
