<p>A room temperature vulcanizing (RTV) silicone composition curable in the presence of moisture with rapid development of green strength. The RTV silicone composition comprises (A) 0 to about 85 weight percent polydiorganosiloxanes comprising on average at least 1.2 chain terminations per molecule selected from the group consisting of hydroxysilyl groups and alkoxysilyl groups; (B) about 10 to 95 weight percent polydiorganosiloxanes comprising on average at least 1.2 chain terminations per molecule selected from the group consisting of hydroxysilyl groups, alkoxysilyl groups, and multi-alkoxysilyl groups, provided that at least one chain termination per molecule comprises a multi-alkoxysilyl group; (C) an effective amount of a condensation catalyst; (D) 0 to about 40 weight percent of an alkoxysilane; and (E) 0 to about 60 weight percent of a filler; provided that the sum of the weight percents of Components (A) and (B) comprises about 20 to 95 weight percent based on the total weight of the RTV silicone composition.</p> |
