Title:
UV CURABLE SILICONE ADHESIVE COMPOSITION AND CURED PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/116126
Kind Code:
A1
Abstract:
This UV curable silicone composition contains (A) an organopolysiloxane represented by general formula (1) [R1 represents a monovalent hydrocarbon group having 1-20 carbon atoms, R2 represents an aromatic group, X represents a group represented by formula (2), a, m, and n respectively represent numbers in the ranges of 1≤a≤3, 1≤m≤2,000, 1≤n≤ 2,000, and m/(n+m)≥0.01 is satisfied. (R1 is as defined above. R3 represents an oxygen atom or an alkylene group having 1-20 carbon atoms, R4 represents an acryloyloxyalkyl group, a methacryloyloxyalkyl group, an acryloyloxyalkyloxy group, or a methacryloyloxyalkyloxy group, p represents a number in the range of 0≤p≤10, and c represents a number in the range of 1≤c≤3.)], (B) a mono-functional (meth)acrylate compound not containing a siloxane structure, and (C) a photopolymerization initiator, and provides, as a temporary fixing material, a cured product having excellent adhesiveness and rubber strength.
