Abstract
Heat-vulcanizable organopolysiloxane compositions, adopted for curing into silicone elastomers having improved reversion and oil resistance and useful, e.g., as seals in contact with hot oils, comprise at least one diorganopolysiloxane resin (A) having a viscosity of greater than 1,000,000 mPa.s at 25.degree. C., a reinforcing and/or semireinforcing filler material (B), an organic peroxide (C), an organosilicon compound (D) containing at least one acryloyloxyalkyl or methacryloyloxyalkyl group bonded to a silicon atom, and (E) at least one oxide or hydroxide of an alkaline earth metal.
