Patent ID: 7288322

Claim:
Addition cross-linking silicone-rubber blend comprising: a) at least one linear or branched organopolysiloxane having at least two alkenyl groups with a viscosity of 0.01 to 30,000 Pa·s, b1) at least one organohydrogen siloxane having 30 to 200 MeHSiO units per molecule and a content of more than 7 mmol SiH/g that contains no aromatic groups, b2) at least one organohydrogen siloxane with at least two SiH units per molecule and at least one aromatic group is contained in the molecule, whereby the characteristics b1) and b2) are implemented in different organohydrogen siloxanes, c) at least one Pt, Ru and/or Rh catalyst, d) at least one alkoxysilane or at least one alkoxysiloxane, or at least one of each, each of which has at least one epoxy group, e) optionally at least one inhibitor, f). optionally at least one filler, optionally surface-modified, and g) optionally at least one additive, whereby the molar ratio of the entire quantity of the SiH groups to the total quantity of Si-bound alkenyl groups of all components in the mixture is at least 0.7.
