Patent ID: 7335708

Claim:
An addition-cross-linking two-component silicone material consisting essentially of a) an organopolysiloxane having at least two vinyl groups in the molecule or a mixture of two or more organopolysiloxanes, each having different chain length and each having at least two vinyl groups in the molecule, as well as b) at least one organohydropolysiloxane having two or more SiH groups in the molecule and c) at least one catalyst, wherein the organopolysiloxane is an organopolysiloxane of the general formula I CH 2 ═CH—SiR 1 R 2 O—(SiR 1 R 2 O) n —SiR 1 R 2 —CH═CH 2 , in which R 1 and R 2 are identical or different and are selected from the group comprising alkyl groups, aryl groups, aralkyl groups, halogen-substituted alkyl groups, halogen-substituted aralkyl groups, cyanoalkyl groups, cycloalkyl groups and cycloalkenyl groups, or wherein the mixture of two or more organopolysiloxanes contains, relative to the total quantity of the two-component silicone material, more than 1% by weight of at least one such organopolysiloxane of the general formula I, wherein the content of divinylorganodisiloxanes or of divinylorganodisiloxane substructures or of divinylorganodisiloxanes and of divinylorganodisiloxane substructures in said two-component silicone material is less than 0.6% by weight, relative to the total weight of the silicone material; and wherein the at least one organopolysiloxane of general formula I has a chain length n of between 1 and 5; d) 0 to 80% by weight of at least one reinforcing filler, e) 0 to 90% by weight of at least one non-reinforcing filler, f) 0 to 5% by weight of at least one dye, g) 0 to 30% by weight of at least one moisture binder, h) 0 to 1% by weight of at least one inhibitor, I) 0 to 80% by weight of at least one vinyl-group-containing or SiH-group containing MQ resin, j) 0 to 80% by weight of at least one compound of organopolysiloxanes and reinforcing fillers, k) 0 to 10% by weight of at least one surfactant, emulsifier or stabilizer, l) 0 to 90% by weight of at least one radioopaque substance, m) 0 to 20% by weight of at least one H 2 absorber or H 2 adsorber or substance that reduces or eliminates H 2 evolution, and n) 0 to 20% by weight of at least one compound that enhances optical readability/scanning.
