Abstract
The invention relates to new, cross-linkable compounds containing (A,) linear organopolysiloxanes with aliphatically unsaturated hydrocarbon radicals, said organopolysiloxanes being of general formula (I) R,R,SiO(R,SiO),[R,Si—Y—SiR,O(R,SiO),],SiR,R,, wherein R can be the same or different, and represents a monovalent, optionally halogenated hydrocarbon radical which is free of terminal aliphatic carbon—carbon multiple bonds, R,represents a monovalent aliphatically unsaturated hydrocarbon radical, Y represents a bivalent organic radical which is free of terminal aliphatic carbon—carbon multiple bonds, a is 0 or 1, b is 0 or 1, and the sum of a+b per molecule is 1 or 2, c is a whole number to the value of 1 to 1000, d is 0 or a whole number to the value of 1 to 10, and optionally, (A,) MQ silicone resins which are soluble in (A,), on the condition that if MQ silicone resins (A,) are not used, the sum of a+b in the formula (I) is 1.3 to 1.9 on average and that if MQ silicone resins (A,) are used, the sum of a+b in formula (I) is 1.0 to 1.9 on average; (B) organo-silicon compounds with Si-bonded hydrogen atoms; (C) catalysts which promote the formation of an aliphatic multiple bond by Si-bonded hydrogen; and optionally, (D) agents which slow down the formation of an aliphatic multiple bond by Si-bonded hydrogen at room temperature.
