Patent ID: 7071278

Claim:
A crosslinkable material based on organosilicon compounds having at least two hydrolyzable groups, wherein at least one organotin compound (C) is contained as a catalyst, said organotin compound (C) comprising the reaction product of phosphorus compounds (i) having C—P(═O) (OH) units and sulfur compounds (ii) having —SO 3 H groups and tin compounds (iii) containing units of the formula R a (XR′) b SnX (4-a-b)/2 (III) in which R are identical or different and are monovalent, optionally substituted hydrocarbon radicals optionally interrupted by oxygen atoms, X are identical or different and are —O— or —S—, R′ are identical or different and are a hydrogen atom or a monovalent, optionally substituted hydrocarbon radical optionally interrupted by oxygen atoms or by optionally substituted silyl radicals, a is 0, 1, 2, or 3 and b is 0, 1, 2, or 3, with the proviso that the sum a+b is less than or equal to 4, said crosslinkable material further comprising at least one amino-funtional organosilicon compound (D).
