Document Type and Number:
WIPO Patent Application WO/2022/170507
Kind Code:
A1
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.
