Patent ID: 8217113

Claim:
A storage stable condensation-crosslinkable RTV-1 composition prepared by mixing components of the composition together with the substantial exclusion of water and which cures upon exposure to water, comprising: (B) at least one heterocyclic compound of the formula A[CR 1 2 SiR a (OR 2 ) 3-a]x (I) in which A is a radical derived from a heterocycle AH x containing at least one ring-forming element of the 3 rd and/or 5 th main groups of the periodic table, in which x hydrogen atoms are replaced by chemical bonds to the CR 1 2 radical, at least one of these bonds being present at a ring-forming element of the 3 rd or 5 th main group, R are identical or different monovalent, optionally substituted hydrocarbon radicals, R 1 are identical or different and are hydrogen or monovalent optionally substituted hydrocarbon radicals, R 2 are identical or different and are monovalent optionally substituted hydrocarbon radicals, a is 0 or 1, and x is 1, 2 or 3, and/or the partial hydrolysates thereof, with the proviso that when radical A contains carbon atoms having oxygen or sulfur atoms bonded via a double bond, these carbon atoms have no direct bond to a ring-forming heteroatom of the 3 rd or 5 th main group of the periodic table which is bonded to a CR 1 2 radical if formula (I).
