product description
H620 is a versatile silicone intermediate, usually they are used as silicone end capping agents. Since the molecular structure contains active hydrogen atoms, it can synthesize copolymer polymers by addition of other organic substances with unsaturated bonds through the hydrosilylation reaction, and a series of active silicone oils can be made from them. Through the above approach, the excellent properties of silicone and the advantages of large amount and low price of general-purpose resin/rubber can be effectively exerted, and some defects in the high price of organic silicon and the performance of general-purpose resin/rubber can be overcome.
