<p>An addition curable silicone pressure sensitive adhesive composition having high lap shear strength particularly at elevated temperatures is described; containing (A) an aromatic soluble, MQ resin or resinous copolymer having R3SiO+E,fra 1/2+EE and SiO+E,fra 4/2+EE ; (B) an alkenyl-containing polydiorganosiloxane having a viscosity of at least about 3,000 centipoise at 25 DEG C.; (C) a set of multi-functional silicones as crosslinkers; (D) from 0 to about 100 parts by weight of a reaction mixture containing from 60 to 100 parts by weight of Component (A) and from about 40 to 0 parts by weight of Component (B); (E) a hydrosilylation catalyst; and optionally (F) from 0 to about 40% by weight of an organic solvent.</p> |
