Title:
ULTRAVIOLET-CURABLE PRESSURE-SENSITIVE SILICONE ADHESIVE COMPOSITION AND CURED OBJECT OBTAINED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2018/225430
Kind Code:
A1
Abstract:
An ultraviolet-curable pressure-sensitive silicone adhesive composition which comprises: 100 parts of an organopolysiloxane (A) having, in the molecule, two groups represented by general formula (1) (wherein R1 represents a C1-20 monovalent hydrocarbon group, R2 represents an oxygen atom, etc., R3 represents an acryloyloxyalkyl group, etc., p and a respectively indicate numbers satisfying 0≤p≤10 and 1≤a≤3); 1-500 parts of a monofunctional (meth)acrylate compound (B) containing no siloxane structure and/or a polyfunctional (meth)acrylate compound (C) containing no siloxane structure; 1-5,000 parts of an oranopolysiloxane resin (D) comprising R4
3SiO1/2 units (a) (wherein R4 represents a C1-10 monovalent hydrocarbon group) and SiO4/2 units (b), the (a)/(b) molar ratio being (0.6-1.2)/1; and 0.01-20 parts of a photopolymerization initiator (E). This composition has satisfactory applicability and curability and gives a cured object which, when used as a temporary fixer, has excellent tackiness and strength.
