Patent ID: 6984707

Claim:
A moisture-curable one part silicone elastomer composition, comprising: at least one organosilicon compound bearing at least two hydrolyzable groups; and a catalyst composition comprising at least one organotin compound containing units of the formula R a R 1 b (XR 3 ) c SnX (4-a-b-c)/2 (I), where R is a monovalent, optionally substituted hydrocarbon radical optionally interrupted by one or more non-adjacent oxygen atoms, X is —O— or —S—, R 1 is —OS(═O) 2 R 2 , R 2 is an amine radical bonded via nitrogen, a monovalent, optionally substituted hydrocarbon radical which may be interrupted by —S(═O) 2 —, or a radical —OR 4 with R 4 having the meaning stated for R 3 , R 3 is a hydrogen atom or a monovalent, optionally substituted hydrocarbon radical optionally interrupted by one or more non-adjacent oxygen atoms, wherein each R, X, R 1 , R 2 , R 3 , and R 4 may be identical or different, a is 0, 1, 2 or 3, b is 0, 1, 2 or 3, c is 0, 1, 2 or 3, with the proviso that the sum a+b+c is <4 and the organotin compound has at least one radical R 1 , and at least one compound containing basic nitrogen, wherein one compound containing basic nitrogen is an amino-functional organosilicon compound.
