Uses: structural control agent used in the preparation of silicone rubber, chain extender used in the synthesis of silicone products and raw materials used in the synthesis of silicone oil. It is an important raw material for the production of silicone resin, benzyl silicone oil and waterproof agent. At the same time, it is easy to hydrolyze and can form alkali metal silanol salt with alkali metal hydroxide. It can also be used as crosslinking agent of RTV silicone rubber.
Use: used as chemical reagent and raw material for synthesis of polymer organosilicon compound.
