Patent ID: 7049385

Claim:
A moisture curable organosiloxane composition comprising: I. a base portion comprising: A. a curable liquid polydiorganosiloxane containing at least two silanol or hydrolyzable groups per molecule; B. a filler containing hydroxyl groups; and II. a curing agent portion comprising: C. an amount of crosslinking agent sufficient to crosslink said composition in the presence of moisture, said crosslinking agent comprising an organosilicone compound containing at least three silicone-bonded hydrolyzable groups per molecule; D. an amount of catalyst sufficient to promote crosslinking of said composition; E. an amount of thixotropic agent sufficient to impart thixotropy to said composition said thixotropic agent comprising a liquid organosiloxane copolymer, said liquid organosiloxane copolymer, comprising a mixture of a silicone-polyether block copolymer and free polyether; and F. an amount of thixotropic enhancing diluent, comprising a C 2 –C 24 aliphatic diol, sufficient to enhance the thixotropic effectiveness of said thixotropic agent in said composition.
