Abstract
A 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 R SiX wherein each R 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 —OR or —OCH CH OR ; (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 having at least an outer surface of a metal selected from the group consisting of silver, gold, platinum, palladium, and 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. A silicone adhesive and a multi-part curable silicone composition.
