CM,1. A room temperature vulcanizable composition having thermally conductive properties which is stable in the absence of moisture, but when exposed to moisture cures to an elastomer, said composition comprising a hydroxyl-terminated organopolysiloxane, a crosslinking agent having an average of at least two hydrolyzable groups per molecule, in which the hydrolyzable groups are selected from the group consisting of acyloxy, amino, oximo, aminoxy, acylamino and phosphato groups, and from 30 to 95 percent by weight of a filler, based on the weight of the composition of which from 30 to 100 percent by weight based on the weight of the filler is silicon nitride particles.
