HMS -991

Technical Datasheet | Supplied by Gelest
Polymethylhydrosiloxanes. It exhibits the highest compressibility of the silicone fluids, 9.32% at 20,000 psi and the lowest viscosity temperature coefficient, 0.50. This trimethylsiloxy terminated hydride functional homopolymers undergoes three main classes of reactivity: hydrosilylation, dehydrogenative coupling and hydride transfer. It is a versatile low cost hydride transfer reagent with the hydride equivalent weight of 60. The reactions are catalyzed by Pd0 or dibutyltin oxide and the choice of reaction conditions lead to chemo selective reduction, e.g. allyl reductions in the presence of ketones and aldehydes. Used as water-proofing agents, reducing agents, components in some foamed silicone systems and in encapsulant applications.
