Abstract
A silicone pressure sensitive adhesive composition includes an alkenyl-terminated polydiorganosiloxane, a polyorganosilicate resin, a polyorganohydrogensiloxane crosslinker, a hydrosilylation reaction catalyst, a hydrosilylation reaction inhibitor, and a solvent. The composition cures to form a pressure sensitive adhesive with selective adhesion to different substrates, including urethane foam. The pressure sensitive adhesive composition, pressure sensitive adhesive, and urethane foam article including the pressure sensitive adhesive are useful in electronics applications for the protection of display devices.
