Abstract:
An organopolysiloxane adhesive composition, comprising, in weight percent based on the total weight of component (A) through (D) of the composition:(A) from about 2% to about 20% of at least one organopolysiloxane rubber base;(B) from about 10% to about 25% of at least one organopolysiloxane pressure sensitive adhesive;(C) from about 30% to about 80% of at least one aliphatic unsaturation-functional organopolysiloxane M'Q resin;(D) from about 1% to about 20% of at least one Si--H functional organopolysiloxane crosslinking agent containing minimally 3 Si--H bound hydrogens per molecule on average;components (A) through (D) dissolved in(E) sufficient organic solvent to obtain a solids content of ingredients (A) to (D) of from 30 percent to about 70% based on the total weight of the adhesive,wherein the sum of the weight percentages of components A to D is 100% based on the weight of components A to D, and wherein following evaporation of solvent, a non-tacky film is formed.
