Novel organopolysiloxanes and room temperature curable organopolysiloxane compositions containing the same

摘要

The invention provides a novel and improved room temperature curable organopolysiloxane composition which is very stable over a long period of time if stored under an anhydrous condition but readily curable on exposure to moisture-containing atmosphere without producing no condensation products having toxicity, unpleasant odor or corrosiveness. The composition comprises, as the main component, an organopolysiloxane having at least three alkenyloxy groups bonded to the silicon atom or atoms in the organopolysiloxane molecule through a silhydrocarbylene linkage, e.g. silethylene linkage, and a curing accelerator.
