Used in
Polydimethylsiloxane is odorless and non-toxic. It has physiological inertness, good chemical stability, electrical insulation and weather resistance. It has a wide viscosity range, low freezing point, high flash point, good hydrophobicity and high shear resistance. It is used for a long time at a temperature of 50 to 180℃. It is widely used as insulation, lubrication, shockproof, dustproof oil, dielectric fluid and heat carrier, and is also used as an additive for defoaming, mold-releasing, paints and daily cosmetics.
The fluorosilicone and siloxane copolymers terminated with silicon-fluorine bonds introduce silicon-amine segments as active groups that can react with double bonds, hydroxyl groups and other groups.
