Abstract:
1. A silicone-based pressure-sensitive adhesive comprising: (A) a mixture or a partial condensation product of (a) a raw rubberlike organopolysiloxane having an average of at least one alkenyl group per molecule, and (b) an organopolysiloxane resin consisting essentially of R (B) an organopolysiloxane having an average of at least two silicon-bonded hydrogen atoms per molecule, wherein the silicon-bonded hydrogen atoms of this component are present in an amount of 0.5 to 150.0 moles per 1 mole of the alkenyl groups in component (A); (C) a phenol-type oxidation inhibitor and/or a phenol-modified organosiloxane in an amount of 0.001 to 10 parts by weight per 100 parts by weight of the sum of components (A) and (B); (D) an aromatic amino-type oxidation inhibitor and/or aromatic amino-modified organosiloxane in an amount of 0.001 to 10 parts by weight per 100 parts by weight of the sum of components (A) and (B); and (E) a platinum-based catalyst in an amount sufficient for curing the adhesive.
