Abstract
(EN)
An ultraviolet curable silicone adhesive composition which contains (A) an organopolysiloxane represented by formula (1) (wherein each R1 represents a polymerizable group or a monovalent hydrocarbon group having 1-20 carbon atoms, provided that at least one of the R1 moieties represents a polymerizable group; R2 represents an oxygen atom or an alkylene group having 1-20 carbon atoms; and m and n represent numbers satisfying m ≥ 0, n ≥ 1 and 1 ≤ (m + n) ≤ 1,000), (B) an organopolysiloxane resin which is composed of (a) an R33SiO1/2 unit (wherein R3 represents a monovalent hydrocarbon group having 1-10 carbon atoms) and (b) an SiO4/2 unit, with the molar ratio of the unit (a) to the unit (b) being 0.6-1.2:1, (C) a fine silica powder and (D) a photopolymerization initiator, and which does not contain a (meth)acrylate compound that does not have a siloxane structure. This ultraviolet curable silicone adhesive composition enables the achievement of a cured product that has good shape retainability and little curing shrinkage, while exhibiting excellent adhesiveness if used as a provisional fixing material.

L'invention concerne une composition adhésive de silicone durcissable aux ultraviolets qui contient (A) un organopolysiloxane représenté par la formule (1) (dans laquelle chaque R1 représente un groupe polymérisable ou un groupe hydrocarboné monovalent ayant de 1 à 20 atomes de carbone, à condition qu'au moins l'une des fractions R1 représente un groupe polymérisable ; R2 représente un atome d'oxygène ou un groupe alkylène ayant 1 à 20 atomes de carbone ; et m et n représentent des nombres satisfaisant m ≥ 0, n ≥ 1 and 1 ≤ (m + n) ≤ 1,000), (B) une résine d'organopolysiloxane qui est composée de (A) une unité R3 3SiO1/2 1/2 (où R3 représente un groupe hydrocarboné monovalent ayant 1 à 10 atomes de carbone) et (b) une unité SiO4/2, le rapport molaire de l'unité (a) à l'unité (b) étant de 0,6 à 1,2/1, (C) une fine poudre de silice et (D) un initiateur de photopolymérisation, et qui ne contient pas de composé (méth) acrylate qui n'a pas de structure siloxane. Cette composition adhésive de silicone durcissable aux ultraviolets permet d'obtenir un produit durci qui a une bonne aptitude à la rétention de forme et un faible retrait de durcissement, tout en présentant une excellente adhésivité si elle est utilisée en tant que matériau de fixation provisoire.
