(JA) 紫外線硬化型シリコーン粘着剤組成物およびその硬化物
Abstract:
(EN) This composition contains (A) 100 parts of an organopolysiloxane having two groups represented by general formula (1) (R1 represents a monovalent hydrocarbon group having 1-20 carbon atoms, R2 represents an oxygen atom or the like, R3 represents an acryloyloxyalkyl group or the like, p represents a number satisfying 0 ≤ p ≤ 10, and "a" represents a number satisfying 1 ≤ a ≤ 3) per molecule, (B) 1-500 parts of a monofunctional (meth)acrylate compound not containing a siloxane structure, (C) 1-5,000 parts of an organopolysiloxane resin containing (a) an R43SiO1/2 unit (in the formula, R4 represents a monovalent hydrocarbon group having 1-10 carbon atoms) and (b) a SiO4/2 unit, where the molar ratio of the unit (a) to the unit (b) is in the range of 0.6 to 1.2:1, (D) 1-100 parts of fine powder silica, and (E) 0.01-20 parts of an optical polymerization initiator. The compound has good shape retention properties and curability for irradiation with ultraviolet light, and provides a cured product which has excellent adhesion suitable for a temporary fixing material.
(FR) L'invention concerne une composition qui contient (A) 100 parties d'un organopolysiloxane ayant deux groupes représentés par la formule générale (1) (dans la formule R1 représente un groupe hydrocarboné monovalent ayant 1 à 20 atomes de carbone, R2 représente un atome d'oxygène ou similaire, R3 représente un groupe acryloyloxyalkyle ou similaire, p représente un nombre satisfaisant à la relation 0 ≤ p ≤ 10 et « a » représente un nombre satisfaisant à la relation 1 ≤ a ≤ 3) par molécule, (B) 1 à 500 parties d'un composé (méth)acrylate monofonctionnel ne contenant pas de structure siloxane, (C) 1 à 5 000 parties d'une résine d'organopolysiloxane contenant (a) un motif R4 3SiO1/ 2 (dans la formule, R4 représente un groupe hydrocarboné monovalent ayant 1 à 10 atomes de carbone) et (b) un motif SiO4/ 2, le rapport molaire du motif (a) au motif (b) étant dans la plage de 0,6 à 1,2:1, (D) 1 à 100 parties de silice en poudre fine et (E) 0,01 à 20 parties d'un initiateur de photopolymérisation. Le composé a de bonnes propriétés de rétention de forme et une aptitude au durcissement par exposition à de la lumière ultraviolette et fournit un produit durci qui a une excellente adhérence appropriée pour une matière de fixation temporaire.
