Characteristics of vinyl silicone oil: 1. The two ends of vinyl group have strong reaction activity. Under the action of catalyst,vinyl group can react with hydrosilicone and participate in many other reactions. 2. Compared with methyl silicone oil, it is more soluble with other organic materials. 3. With active double bond, it is easy to react with polyurethane, acrylic acid and other organic compounds.
Industrial use: 1. It can be used as hardener and diluent of high viscosity 110-2 silicone rubber. 2. It is used as modifier for some organic materials, such as acrylic resin and vinyl acetate resin. 3. It is used to manufacture high temperature vulcanized silicone rubber, medium temperature vulcanized silicone rubber and silicone gel.
