DissolvabilityBe soluble in organic solvent. Be easy to be hydrolyzed and alcoholized. In order to reduce Hydrolysis speed, mixed solvent of water, acetone or methylbenzene should be applied when make aqueous solution.
UsesIt is the major material for compounding other vinyl organic silicon coupling agents. Be applied to modification of chloric resin (such as polyvinyl chloride etc.) or the copolymerizing with chloric monomer. It contains unsaturated group and active chloride in CG-150 and hydrolyzes furiously with water and produces relative silanol. Also, it can be used as glass fiber surface treating agent or plastic layers strengthening treating agent to improve products’ intensity, heat-resistance and damp-resistance. Be applied to surface treatments for glass fiber. It can improve the adhesiveness, heat-resistance and water-resistance of glass fiber, non-saturated polyester, epoxy resin and acrylic resin.

Trichlorovinylsilane: Guide

Vinyltrichlorosilane is a highly flammable liquid with a melting point of -95℃.

1. It is used for the surface treatment of glass fiber and the treatment of reinforced plastic laminates. It can have condensation reaction with silanol on the surface of glass and form covalent bond with glass, so as to improve the adhesion, heat resistance and water resistance of glass fiber and unsaturated polyester, epoxy resin, acrylic resin, etc.
It is also used as filler silica for rubber. It is also used as coupling agent of silicon dioxide as filler for rubber, modifier of chlorine-containing resin and raw material for synthesizing many kinds of silicone products.

2. Used in the synthesis of silicone compounds, used as intermediates in the manufacture of silicone, coupling agent for adhesives.
