摘要
FIELD: chemistry.;SUBSTANCE: invention discloses a multi-component composition of siloxane rubber which solidifies at room temperature, containing at least: (A) diorganopolysiloxane, (B) a silicon compound containing a methoxy group, containing bis(methoxy silyl)alkane or organomethoxysilane (except organotrimethoxysilane containing an amine group) (B-1) carbasilatrane derivative containing a methoxy group (B-2), and aminoalkylmethoxysilane (B-3), where the weight ratio of components (B-2) and components (B-3) lie between (20:80) and (80:20); and (C) a curing agent, where the composition is packed in form of two or more separately stored compositions, where neither of the said separately stored compositions contains all the said components (A), (B) and (C) simultaneously. The composition is suitable for use as a sealant and adhesive agent for construction materials on open air and in places with water.;EFFECT: preparation of a composition which avoids deterioration of adhesive properties of obtained rubber in severe conditions, for example after immersion in hot water, with preservation of rate of hardening of the composition.;10 cl, 5 tbl, 4 ex
