Vinyl Terminated Silicone Fluid: Guide

Methyldichlorosilane is a basic silicone raw material, mainly used in the production of hydrogen-containing silicone oils, methyl vinyl monomers and aminosilanes, penetrating water repellents and so on.

Methyldichlorosilane can be prepared by silicon hydrogenation reaction, thermal condensation reaction, hydrolysis reaction and alcoholysis reaction of methyl dichlorosilane.

Methyl chloropropyl dichlorosilane, methyl vinyl dichlorosilane, methyl trifluoropropyl dichlorosilane, methyl phenyl dichlorosilane, methyl hydrogen-containing cyclic body and hydrogen-containing silicone oil can be prepared.
