Methyltrichlorosilane (MTCS): Guide

Methyltrichlorosilane is a kind of production of various organosilicon compounds, which is the main raw material for the production of water repellent, fumed silica, methyl silicone resin and polysiloxane. This product is extremely volatile at room temperature, and easily generates hydrochloric acid and white powdery substance when it meets water. It is easy to decompose when heated and generate hydrogen chloride.

Methyltrichlorosilane can be used in the production of various organosilicon compounds, and is the main raw material for the production of water repellents, fumed silica, methylsilicon resins and polysiloxanes.The vapor and liquid of M1 can cause burns to the skin, and is toxic by inhalation. React with anhydrous ethanol to produce methyltriethoxysilane.
