Composition stable under substantially anhydrous conditions and curable to the solid, elastic state in the presence of moisture which comprises a silanol chain-stopped polydiorganosiloxane in which the organo groups are selected from the group consisting of hydrocarbyl, halohydrocarbyl and cyanoalkyl and an imidatosilane of the formula WHEREIN R5 and R6 are each aliphatic hydrocarbyl, a is an integer of 2 to 4, inclusive, b is an integer of 0 to 2, inclusive, d is an integer of 0 to 1, and the sum of a, b and d is 4. WHEREIN R4 is an organic radical selected from the group consisting of aliphatic hydrocarbyl, aliphatic halohydrocarbyl, aliphatic nitrohydrocarbyl, and WHEREIN R1 is an organic radical of not more than 18 carbon atoms selected from the group consisting of hydrogen, hydrocarbyl, halohydrocarbyl and cyanoalkyl, R. and R2 are each organic radicals of not more than 18 carbon atoms selected from the group consisting of hydrocarbyl, halohydrocarbyl, nitrohydrocarbyl and alkoxyhydrocarbyl, R3 is an organic radical of not more than 18 carbon atoms selected from the group consisting of hydrogen, hydrocarbyl, halohydrocarbyl, nitrohydrocarbyl, alkoxyhydrocarbyl, dialkylamino and |
