Patent ID: 7566750

Claim:
A composition comprising (A) at least one organopolysiloxane comprising units of the formula R a (R 1 O) b SiO (4-a-b)/2 (I), in which R are identical or different and are a hydrogen atom or a monovalent, SiC-bonded, optionally substituted hydrocarbon radical, R 1 are identical or different and are a hydrogen atom or a monovalent, optionally substituted hydrocarbon radical, a is 0, 1, 2 or 3, and b is 0, 1, 2 or 3, with the proviso that the sum a+b is a positive integer less than or equal to 3 and the organopolysiloxanes are composed of 5 to 50,000 units of the formula (I), (B) 0.1 to 30 parts by weight, based on 100 parts by weight of component (A), of at least one additive selected from (B1) filler particles and/or (B2) organopolysiloxane resin comprising units of the formula R 2 c (R 3 O) d SiO (4-c-d)/2 (II), in which R 2 are identical or different and are a hydrogen atom or a monovalent, optionally substituted, SiC-bonded hydrocarbon radical, R 3 are identical or different and are a hydrogen atom or a monovalent, optionally substituted hydrocarbon radical, c is 0, 1, 2 or 3, and d is 0, 1, 2 or 3, with the proviso that the sum c+d is less than or equal to 3 and in less than 50% of all units of the formula (II) in the organopolysiloxane resin the sum c+d is 2, and (C) 0.005 to 1.0 part by weight of water, based on 100 parts by weight of component (A) which is added to the remaining components.
