HMS -064 by Gelest (Mitsubishi Chemical) is 5-7% (Methylhydrosiloxane) and 93-5% (dimethyl-siloxane copolymer). This trimethylsiloxy terminated hydride functional polymer undergoes three main classes of reactivity: hydrosilylation, dehydrogenative coupling and hydride transfer. HMS -064 has more readily controlled reactivity than the homopolymers which results in tougher polymers with lower cross-link density. The preferred catalysts for the reactions are platinum complexes such as SIP6830.3 and SIP6832.2. In principle, the reaction of hydride functional siloxanes with vinyl functional siloxanes takes place at 1:1 stoichiometry. HMS -064 is used in encapsulant applications.

HMS -991 by Gelest (Mitsubishi Chemical) is 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 Pd<sup>0</sup> 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. HMS -991 is used as water-proofing agents, reducing agents, components in some foamed silicone systems and in encapsulant applications.
