Adhesion promoters for one-component RTV silicone compositions

Claim 1

A stable, one-package, substantially anhydrous and substantially acid-free, room temperature vulcanizable organopolysiloxane composition stable under ambient conditions in the substantial absence of moisture over an extended period of time and convertible to a tack-free elastomer comprising: (1) an organopolysiloxane wherein the silicon atom at each polymer chain end is terminated with at least two alkoxy radicals; (2) an effective amount of a condensation catalyst; (3) a stabilizing amount of scavenger for hydroxy functional groups; (4) an effective amount of a curing accelerator selected from the group consisting of substituted guanidines, amines and mixtures thereof; and (5) an effective amount of an adhesion promoter having the formula ##STR39## where R 10 and R 11 are C 1-8 monovalent hydrocarbon radicals, t varies from 0 to 3, and Z is a saturated, unsaturated or aromatic hydrocarbon radical, said radical being further functionalized by a member selected from the group consisting of amino, ether, epoxy, isocyanato, cyano, isocyanurate, acryloxy and acyloxy and mixtures thereof.
