Self-bonding, 1-package, room-temp. and moisture-curable silicone compns, contain a silanol-terminated poly(diorganosiloxane), a tri- or tetrafunctional fluid polysiloxane, silica, a siloxane crosslinker which evolves low volatility carboxylic acid fragments on hydrolysis, and a Sn-contg. silanol condensation catalyst. The cured rubbers have excellent heat and oil resistance and are useful as sealants between metal surfaces in automobile engines. Thus, 100 parts mixt. contg. silanol-terminated poly(dimethylsiloxane) 100, silicone oil 10, Fe oxide 6, and dimethylsiloxane-treated fumed silica 25 parts was mixed with a catalyst.
