ABSTRACT:
The room-temperature curable silicone rubber composition is formulated, in addition to the conventional ingredients of a hydroxy-terminated diorganopolysiloxane and an organosilicon compound having at least two hydrolyzable groups in a molecule, a substantial amount of an alkali metal salt of a weak acid having an acid dissociation constant as expressed by pK.sub.a in the range from 2.0 to 12.0 at 25.degree. C. such as acrylic, methacrylic, benzoic and acetic acids. By virtue of this unique ingredient compounded therein, the composition of the invention can give a vulcanized rubber having outstandingly high resistance against oils used in automobiles even at elevated temperatures.
