Abstract:
A curable silicone composition for preparing a silicone adhesive, the composition prepared by mixing:(A) an organopolysiloxane containing an average of at least two silicon-bonded hydroxy groups per molecule; (B) a crosslinking agent in an amount sufficient to cure the composition; wherein the agent is selected from (i) at least one silane having the formula R2nSiX4âˆ’n wherein each R2 is independently selected from monovalent hydrocarbon and monovalent halogenated hydrocarbon groups having from 1 to about 8 carbon atoms, n is 0 or 1, and X is â€”OR2 or â€”OCH2CH2OR2; (ii) a partial hydrolyzate of (i), and (iii) mixtures comprising (i) and (ii); (C) an electrically conductive filler in an amount sufficient to impart electrical conductivity to the silicone adhesive, wherein the filler comprises particles consisting of silver, gold, platinum, palladium, or alloys thereof; (D) an effective amount of a hydroxy-functional organic compound having a molecular weight up to about 1000 and containing at least one hydroxy group per molecule, provided the compound does not substantially inhibit cure of the composition; and (E) a catalytic amount of a condensation catalyst comprising a metal salt of a carboxylic acid.
