What is Vinyltrimethoxysilane CAS 2768-02-7?
Vinyltrimethoxysilane CAS 2768-02-7 is a colorless transparent liquid with an ester odor, soluble in methanol, ethanol, isopropanol, toluene, acetone, etc. Vinyltrimethoxysilane will slowly hydrolyze when exposed to moisture in the air, producing methanol.
Vinyltrimethoxysilane modifies polyethylene and other polymers by grafting onto the main chain of the polymer, allowing the side chains of the polymer to carry trimethoxysilyl ester groups as active points for warm water crosslinking.

Application
1.Vinyltrimethoxysilane is mainly used for polyethylene cross-linking; Surface treatment of glass fiber plasticized with glass fiber; Synthetic special coatings; Surface moisture-proof treatment of electronic components; Surface treatment of inorganic silicon containing fillers, etc.
2.Vinyltrimethoxysilane is an important crosslinking agent for cross-linked polyethylene and is widely used in the manufacturing of wires, cable insulation, sheath materials, and cross-linked polyethylene pipes. Used for cross-linking polyethylene to manufacture heat-resistant pipes, hoses, and films, making thermoplastic resins and thermosetting resins have better heat resistance, acid and alkali resistance, and superior mechanical strength.
3.Vinyltrimethoxysilane can also be used as a crosslinking agent for ethylene vinyl acetate copolymers, chlorinated polyethylene, and ethylene ethyl acrylate copolymers.
4.Vinyltrimethoxysilane can be copolymerized with acrylic paint to produce a special exterior wall coating, called silicone acrylic exterior wall coating.
5.Vinyltrimethoxysilane can be copolymerized with various monomers (such as ethylene, propylene, butene, etc.), or grafted with corresponding resins to produce modified polymers for special purposes.
6.Vinyltrimethoxysilane is also a good promoter for the adhesion of silicone rubber to metals and fabrics.
