Main use: Used as an intermediate for silicone. It is suitable for unsaturated polyester, acrylic resin, EPDM, etc. It is a good accelerator for the adhesion of silicone rubber and metal.
Store in a cool, dry warehouse. Keep away from the fire and humid environment.

Resolve resolution:
Method 1:
Vinyl trichloro silane reacts with methanol. Then the crude product is neutralized and rectified to obtain the finished product.

Method 2:
The platinum catalyzes the reaction between acetylene and trimethoxy hydrosilane, and the crude product is rectified to obtain the finished product.

Vinyltrimethoxysilane is a colorless and transparent liquid with an ester odor, which can slowly be hydrolyzed in water to generate the corresponding silanol. It is soluble in organic solvents such as methanol, ethanol, isopropanol, toluene, acetone.

This product is a general-purpose organosilane coupling agent, mainly used as a polyethylene crosslinking agent, glass fiber surface treatment agent, synthetic special coatings, surface moisture-proof treatment of electronic components, surface treatment of inorganic silicon-containing fillers, etc.
