Vinyl Terminated Silicone Fluid: Guide
Methyldichlorosilane is a key silicone raw material, primarily used in the production of hydrogen-containing silicone oils, methyl vinyl monomers, aminosilanes, and penetrating water repellents.
It can be synthesized through various methods, including silicon hydrogenation, thermal condensation, hydrolysis, and alcoholysis reactions.
Methyldichlorosilane can also be used to produce a range of compounds, including methyl chloropropyl dichlorosilane, methyl vinyl dichlorosilane, methyl trifluoropropyl dichlorosilane, methyl phenyl dichlorosilane, methyl hydrogen-containing cyclic compounds, and hydrogen-containing silicone oils. These products are widely used in diverse industrial applications.
