Description and Uses

3-Chloropropyltriethoxysilane is the main raw  material for preparing Si-69, KH-550 and other silane coupling agents.  It is also used as a rubber processing aid to couple inorganic fillers  in various halogenated rubber to improve various physical and mechanical  properties. It can also be used to synthesize organosilicon compounds  containing quaternary ammonium cations, as antifungal and odor-proof  finishing agents, with special bactericidal, odor-proof, antistatic and  surface activity.
