3-Methacryloxypropyltriethoxysilane

CAS Number
21142-29-0

Description

Methacryloxy functional silane, the triethoxy analog of the more common trimethoxy methacrylate silane. Copolymerizes with acrylic and vinyl monomers through its methacrylate group while the ethoxy groups bond to glass and mineral surfaces, and is preferred over the methoxy grade where slower cure or lower volatility is wanted.
