Abstract
Room temperature vulcanizable silicone compositions are provided having improved shelf life, primerless adhesion, deep section cure, and low toxicity properties, comprising by weight: A. 100 parts of a polydiorganosiloxane having a viscosity of from about 100 to about 1,000,000 centipoise at 25.degree. C., wherein the silicon atoms at each polymer end chain is terminated with at least two alkoxy radicals, the organic group being a C.sub.1-15 monovalent hydrocarbon radical; B. an effective amount of a diorganotin bis beta-diketonate condensation catalyst; C. from about 0.1 to about 1.5 parts of a scavenger for hydroxy functional groups, preferably a disilazane or polysilazane; D. from about 0.6 to about 5 parts of an adhesion promoting polyalkoxysilane functionalized with ether, epoxy, isocyanato, cyano, acryloxy, and acyloxy, preferably with epoxy; and E. from 0 to about 10 parts of a crosslinking polyalkoxysilane.
