Abstract
A method is provided for making a heat curable organopolysiloxane composition, such as a pressure sensitive adhesive composition by blending a benzene soluble resinous copolymer in the form of a spray dried particulate, comprising triorganosiloxy units, such as trimethylsiloxy units, and SiO.sub.2 units with a fluid network mixture of an alkenyl siloxane, a silicon hydride siloxane and a hydrosilylation catalyst.
