Abstract
(EN) A two-component type room temperature fast-curing organopolysiloxane composition which is a room temperature curing organopolysiloxane composition of a two-component and dealcohol type and which comprises, as curing agents, a first agent containing a hydrolyzable organosilane compound represented by formula (3) and/or a partially hydrolyzed condensation product thereof and a second agent containing a curing catalyst. This composition has particularly excellent fast-curing properties and deep-curing properties and provides a cured product having both high storage stability and high durability. (R6 represents an unsubstituted or substituted monovalent hydrocarbon group having 1-20 carbon atoms; R7 represents an unsubstituted or substituted alkyl group having 1-20 carbon atoms or an unsubstituted or substituted cycloalkyl group having 3-20 carbon atoms; and a is from 1 to 3.)
(FR) L’invention concerne une composition d’organopolysiloxane à durcissement rapide à température ambiante de type bicomposant qui est une composition d’organopolysiloxane durcissant à température ambiante d’un type bicomposant et désalcool et qui comprend, comme agents de durcissement, un premier agent contenant un composé organosilane hydrolysable représenté par la formule (3) et/ou un produit de condensation partiellement hydrolysé associé et un second agent contenant un catalyseur de durcissement. Cette composition a des propriétés de durcissement rapide et des propriétés de durcissement profond particulièrement excellentes et fournit un produit durci ayant tant une grande stabilité au stockage qu’une grande durabilité. (R6 représente un groupe hydrocarboné monovalent non substitué ou substitué ayant 1 à 20 atomes de carbone ; R7 représente un groupe alkyle non substitué ou substitué ayant 1 à 20 atomes de carbone ou un groupe cycloalkyle non substitué ou substitué ayant 3 à 20 atomes de carbone ; et représente 1 à 3).
(JA) 二成分型の脱アルコールタイプの室温硬化性オルガノポリシロキサン組成物であって、硬化剤として下記式(3)で示される加水分解性オルガノシラン化合物及び/又はその部分加水分解縮合物を含む第一剤と、硬化触媒を含む第二剤とからなる二成分型室温速硬化性オルガノポリシロキサン組成物が、とりわけ速硬化性、深部硬化性に優れ、同時に保存安定性、耐久性も良好な硬化物を与える。(R6は炭素数1~20の非置換又は置換の1価炭化水素基、R7は炭素数1~20の非置換若しくは置換のアルキル基、又は炭素数3~20の非置換若しくは置換のシクロアルキル基、aは1~3。)
