ABSTRACT OF THE DISCLOSURE Self-bonding, low modulus, one-package room temperature vulcanizing silicone compositions, curable in the presence of moisture, comprise (a) a silanol chain-stopped polydiorgano- siloxane; (b) a cross-linking silane; and (c) a silanol reactive organometallic ester compound of a metal, the compound having radicals attached to the metal atom, at least one of the radicals being a substituted or unsubstituted hydrocarbonoxy radical, attachment being through M-O-C linkages, where M is the metal, and any remaining valances of M are satisfied by other organo radicals attached to M through such linkages, or an -OH, -O- or M-O-M linkage, the weight ratio of components (c) to (b) always being at least unity. Such compositions have unusually high adhesion to a variety of difficulty bondable substrates.
