Abstract
A process for preparing a solventless pressure sensitive adhesive composition comprising mixing (A) a solid polyorganosilicate resin component with (B) an aliphatically unsaturated polydiorganosiloxane (B-1), a branched polyorganosiloxane (B-2), or a mixture of (B-1) and (B-2), at certain temperatures, followed by cooling. The solventless pressure sensitive adhesive composition prepared by the process has a low viscosity and can be cured to form pressure sensitive adhesives. The pressure sensitive adhesives are suitable for protective film applications.
