Bis(trimethylsiloxy)methylsilane Description
CFS-887, Bis(trimethylsiloxy)methylsilane with Cas No.1873-88-7 is a colorless clear liquid, also named as Heptamethyltrisiloxane. It possesses highly active silicon-hydrogen bond, which is mainly used to synthesize Si-C type trisloxane surfactants via silyl addition reaction with terminated allyl polyether.
Bis(trimethylsiloxy)methylsilane Application
CFS-887 can be used as an essential silicone intermediate for hydrosilylation of organic compounds containing olefins.
CFS-887 can be used as a basic raw material for synthesis of polyether modified trisiloxane surfactant. The special surfactant with good hydrolysis stability, superior dispersibility and wettability, is suitable for water-borne paints and adhesives.
CFS-887 can be used as an important additive in a wide variety of fields including cosmetics, paints and coating, Polyurethane sponge, and pesticide used in agriculture.
Cas 1873-88-7
CFS-887 can be also used for other functional silicone fluid preparation.
