Patent ID: 8207260

Claim:
A multicomponent RTV composition crosslinkable by condensation reaction comprising at least one component (A) and a component (B), components (A) and (B) separated from each other prior to use, wherein component (A) has at least one organosilicon compound (1) containing at least one unit of the formula [A-CR 1 2 ] c SiR a Y b O (4-a-b-c)/2 (I) in which A are identical or different organic radicals bonded via nitrogen, oxygen, sulfur or phosphorus, R are identical or different, monovalent, optionally substituted hydrocarbon radicals, R 1 are identical or different and are a hydrogen atom or monovalent, optionally substituted hydrocarbon radical, Y are identical or different and are hydrolyzable radicals, a is 0, 1, 2 or 3, b is 0, 1, 2 or 3, and c is 0, 1 or 2, with the proviso that the sum of a+b+c is ≦4 and the organosilicon compound (1) has at least one unit with c differing from 0 and at least two radicals Y, and component (B) contains at least one compound (2) having OH groups, selected from the group consisting of (21) water and (22) organosilicon compounds containing units of the formula R 2 x (OH) y SiO (4-x-y)/2 (II), in which R 2 are identical or different and has a meaning stated for radical R, x is 0, 1, 2 or 3, and y is 0, 1, 2 or 3, with the proviso that the sum of x+y is ≦4 and organosilicon compound (22) has at least two OH groups, and with the proviso that sufficient component (B) is present to cure a mixture of (A) and (B) to a solid elastomer.
