Multi-component room-temperature-curable silicone rubber composition
First Claim
1. A multi-component room-temperature-curable silicone rubber composition comprising at least:
- (A) 100 parts by weight of a diorganopolysiloxane that has a viscosity in the range of 20 to 1,000,000 mPa·
s at 25°
C. and that comprises;
20 to 100 parts by weight of a diorganopolysiloxane (A-1) capped at both molecular terminals with alkoxysilyl groups or hydroxysilyl groups, and 0 to 80 parts by weight of a diorganopolysiloxane (A-2) capped at one molecular terminal with an alkoxysilyl group or a hydroxysilyl group and capped at the other molecular terminal with an alkyl group or an alkenyl group;
(B) a methoxy group-containing silicon compound comprising a bis(methoxysilyl)alkane or an organotrimethoxysilane (except amino group containing organotrimethoxysilane) (B-1), a methoxy group-containing carbasilatrane derivative (B-2), and a N-(β
-aminoalkyl) aminoalkylorganodimethoxysilane or N-(β
-aminoalkyl) aminoalkyltrimethoxysilane (B-3) (wherein constituent (B-1) is used in an amount of 0.5 to 15 parts by weight per 100 parts by weight of component (A), wherein the total amount of constituents (B-2) and (B-3) is in the range of 0.1 to 10 parts by weight per 100 parts by weight of component (A), and wherein the weight ratio of constituent (B-2) to constituent (B-3) is in the range of (20;
80) to (80;
20)); and
(C) 0.001 to 20 parts by weight of a curing catalyst,the composition being packaged as two or more separately stored compositions wherein none of said separately stored compositions contain all said components (A), (B), and (C) simultaneously; and
wherein said methoxy group-containing carbasilatrane derivative (B-2) is of the following general formula;

Abstract
A multi-component room-temperature-curable silicone rubber composition comprising at least: (A) a diorganopolysiloxane, (B) a methoxy group-containing silicon compound comprising a bis(methoxysilyl)alkane or a organotrimethoxysilane (except amino group containing organotrimethoxysilane) (B-1), a methoxy group-containing carbasilatrane derivative (B-2), and an aminoalkylmethoxysilane (B-3) (wherein the weight ratio of constituent (B-2) to constituent (B-3) is in the range of (20:80) to (80:20)); and (C) a curing catalyst,
the composition being packaged as two or more separately stored compositions wherein none of said separately stored compositions contain all said components (A), (B), and (C) simultaneously.
