Methyl silicone oil prone to cross-linking reaction under catalytic Pt catalyst, can be used as liquid silicone rubber crosslinking agent due to the molecule contains a certain number of relatively active Si-H bond. In metal salts, catalytic role, i.e., at a lower temperature to form a hydrophobic film on the surface of various substances, Hydrogen silicone have methyl silicone similar resistance to high temperature resistance, weather resistance, electrical insulation, physical inertia and other properties, and by adjust the hydrogen content, it can be obtained in different viscosity products.
