Abstract
A pressure-sensitive adhesive having an excellent tack and adhesive strength is obtained from a composition which contains an alkenyl group-containing silicone polymer, a tackifying silicone resin having less than one percent hydroxyl content, an organohydrogenpolysiloxne curing agent for the alkenyl group-containing silicone polymer and a platinum-containing catalyst. The composition can be cured to a silicone pressure-sensitive adhesive by heating at relatively low temperatures.
