Vinylsilane
From Wikipedia, the free encyclopedia
Vinylsilane, also called vinyl silane or ethenyl silane, is an organic chemical with chemical formula C2H6Si, or CH2=CH-SiH3. It is a derivate of silane. Its CAS number is [7291-09-0] [1].
Vinylsilane is used as a monomer for some copolymer plastics (eg. ethylene-vinylsilane and ethylene-vinyl acetate-vinylsilane). It is also used as a cross-linking agent during manufacture of cross-linked polyethylene. The silane group is reactive and in the presence of moisture forms cross-links and the material cures. Moisture-curable polymers are used as an electrical insulation in some kinds of cables.
Vinyl silane is also used as a coupling agent for treatment of glass fibers in order to form stronger bond with resin and make fiberglass with better mechanical properties. Aminosilane and epoxy silane are used for the same purpose too. The silane group attaches to the glass substrate via covalent Si-O-Si bond, while the resin reacts with the vinyl-, amino-, or epoxy- group and binds to it.
