Abstract: Compositions and a method for performing the room temperature vulcanization of silicone elastomers are disclosed. The compositions and method utilize specifically-defined hydroxy-terminated polyorganosiloxanes, cross-linking agents which contain a hydrolyzable moiety, a catalyst which exhibits catalytic action in the condensation reaction between the hydroxy groups of the polyorganosiloxanes and the hydrolyzable groups of the cross-linking agents, and a formamide-type cure accelerator component. It has been found that these compositions can be stably stored under substantially moisture-free conditions and be readily vulcanized to form solid elastomers when exposed to moisture in the air. The vulcanization process provides a fast cure and a final silicone rubber product which exhibits good depth of hardening and excellent physical properties.
