1. Organic silane coupling agents are important intermediates that can undergo hydrosilylation reactions with various unsaturated bonds to generate various organic silicon compounds; It is a key raw material for epoxy silane and vinyl silane 2. Addition with acetylene can produce methyl vinyl dimethoxysilane, and addition with various olefins can produce corresponding alkyl silane; 3. MS resin can be prepared by reacting with capped polyether, and alkoxy capped 107 adhesive can be produced by reacting with vinyl capped silicone oil; Important modifiers for other polymer materials; 4. Hydrogen containing silicone resin can be prepared as a bonding promoter for addition molded silicone rubber; Preparation of hydrogen containing silicone oil.
