Trifluoropropyl trimethoxysilane (Cas No. : 429-60-7) combines the excellent properties of organosilicon and organofluorine, and at the same time has a reaction group that can chemically combine with inorganic materials (such as glass, silica sand, metal, etc.) in its molecules, the reaction group that can chemically combine with inorganic materials (such as synthetic resin, rubber, etc.), and can connect the two materials with different properties together. It can improve the properties of composite materials and increase the bond strength. Therefore,3,3, 3-trifluoropropyl trimethoxy-silane is an important fluorine-containing silane coupling agent and an important raw material for the preparation of fluoro-silicone rubber and resin.
