Trichlorovinylsilane Description
Trichlorovinylsilane (CAS 75-94-5), also known as Vinyltrichlorosilane, is a colorless to light yellow fuming liquid with a strong, pungent odor. It is highly soluble in most organic solvents, making it a versatile compound in various industrial applications. Vinyltrichlorosilane is primarily used in organic synthesis as a key intermediate in silicone manufacturing. It plays a critical role in the production of silane-based chemicals. Additionally, it is commonly used as a coupling agent for adhesives, improving the bonding between organic and inorganic materials. Vinyltrichlorosilane also serves as an important chemical reagent in a wide range of chemical reactions.

| Dissolvability | Be 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. |
| Uses | It 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℃, commonly used for surface treatment and silicone synthesis.
Uses:
Surface Treatment: Used to treat glass fiber and reinforced plastic laminates, improving adhesion, heat resistance, and water resistance. It bonds with glass and enhances materials like unsaturated polyester, epoxy resin, and acrylic resin. Also used as a coupling agent for silica fillers in rubber.
Silicone Synthesis: Serves as an intermediate in silicone compound production and as a coupling agent in adhesives.
