Methylvinyldiethoxysilane Description

Methylvinyldiethoxysilane (CAS 5507-44-8) also known as vinylmethyldiethoxysilane or Diethoxymethylvinylsilane, It is a colorless to light yellow fuming liquid with a pungent, pungent odor.

Vinylmethyldiethoxysilane is soluble in most organic solvents, and is mainly used in organic synthesis as an intermediate for silicone manufacturing and as a chemical reagent. Vinyltrichlorosilane is soluble in most organic solvents and is mainly used in organic synthesis, as an intermediate in the manufacture of silicones, as a coupling agent for adhesives and as a chemical reagent.

Methylvinyldiethoxysilane: Guide

Methylvinyldiethoxysilane is mainly used as coupling agent, adhesion promoter, crosslinking agent; it can also be used in sulfur and peroxide rubber, polyester, polyolefin, styrene and acrylic acid, etc.; copolymerization of ethylene and ethylene, used for crosslinking of polyethylene caused by moisture; surface treatment of mineral fillers, etc.

Potential applications of Methylvinyldiethoxysilane
(1) Used as coupling agent, adhesion promoter, and crosslinking agent. Grafted onto polyethylene for wet gas coupling, copolymerized with ethylene for wet gas coupling of polyethylene.

(2) Can be used for surface treatment of plastics, peroxide vulcanized rubber, polyester, polyester, polyolefin styrene, acrylic and other mineral fillers.
