Title:
RELEASE CONTROL AGENT, SILICONE COMPOSITION FOR FORMING RELEASEABLE FILM, AND RELEASE LINER
Document Type and Number:
WIPO Patent Application WO/2022/102688
Kind Code:
A1
Abstract:
The present invention relates to: a release control agent comprising a silicone resin represented by the average unit formula (R1
3SiO1/2
a(SiO4/2
1.0 (in the formula, each R1 independently is a C1-6 alkyl group and a is a number of 0.5-1.5.) and having a weight average molecular weight in terms of standard polystyrene by gel permeation chromatography of 3,000-6,000, and (B) a diorganopolysiloxane having at least two silicon atom-bonded alkenyl groups per molecule and/or (C) a C12-24 α-olefin; and a silicone composition for forming a releaseable film including the same. This silicone composition for forming a releaseable film forms a releaseable film that, although exhibiting relatively large release force relative to an adhesive, undergoes little change in release force after long-term aging with an adhesive adhered and does not lower the residual adhesive strength of an adhesive.
