Abstract
(EN)
Provided is a polyorganosiloxane composition that can be used to obtain a cured product which has low hardness, high transparency, great tensile strength, and low surface adhesiveness. This curable polyorganosiloxane composition contains (A) an alkenyl group-containing polyorganosiloxane having (A1) a polyorganosiloxane having an alkenyl group at both ends thereof and having a predetermined viscosity, (A2) a straight-chain polyorganosiloxane comprising a polyorganosiloxane having, on average, not less than 0.6 but less than 2 of alkenyl groups and having a predetermined viscosity, and (A3) a resin-like polyorganosiloxane, (B) a polyorganohydrogen siloxane comprising (B1) a straight-chain polyorganosiloxane containing Si-H at both ends thereof, and (B2) a polyorganosiloxane having three or more Si-H, and (C) a hydrosilylation reaction catalyst, in amounts that satisfy a predetermined relationship.
(FR)
L'invention fournit une composition de polyorganosiloxane qui permet d'obtenir un objet durci doté d'une faible dureté et d'une transparence élevée, et présentant une grande résistance à la traction et une surface faiblement collante. Plus précisément, l'invention concerne une composition de polyorganosiloxane durcissable, qui comprend, en quantités satisfaisant chacune des relations prédéfinies : (A) un polyorganosiloxane comprenant un groupe alcényle possédant (A1) un polyorganosiloxane à groupe alcényle aux deux extrémités doté d'une viscosité prédéfinie, (A2) un polyorganosiloxane sous forme de chaîne droite constitué d'un polyorganosiloxane possédant possédant en moyenne 0,6 groupe alcényle ou plus à moins de 2 groupes alcényle dotés d'une viscosité prédéfinie, et (A3) un polyorganosiloxane sous forme de résine ; (B) un polyorganohydrogénosiloxane qui est constitué (B1) d'un polyorganosiloxane sous forme de chaîne droite comprenant Si-H aux deux extrémités, et (B2) un polyorganosiloxane possédant trois Si-H ou plus ; et (C) un catalyseur de réaction d'hydrosilylation.
(JA)
