摘要

OIL COMPOSITIONS CONTAINING HIGH AND LOWMOLECULAR WEIGHT POLY(DIMETHYLSILOXANE)ABSTRACTCompositions useful as lubricants or hydraulicfluids are described which consist of a hydrocarbon oilhaving a Saybolt seconds universal viscosity at 100°Fof from 30 to 500 and a flash point greater than 175°Fblended with a mixture of a low viscosity poly(dimethylsiloxane)having a viscosity of from 5 to 1000 centistokes at 25°Cand a high viscosity poly(dimethylsiloxane) having aviscosity of from 10,000 to 1,000,000 centistokes at 25°C.
