Abstract:
1. A curable material comprising: component (A) comprising at least two different types of organopolysiloxanes, (A1) having a viscosity value of 10 to 1,000 mPa-s, and (A2) having a viscosity value of 500 to 45,000 mPa-s, with at least two ethylenically unsaturated groups per molecule, with the proviso that the component (A) siloxanes do not comprise aromatic groups; component (B) comprising organohydrogenpolysiloxane having about 1.0 to about 1.7 wt.- % silicon-bonded hydrogen and with at least three SiH groups per molecule; component (D) comprising a catalyst for promoting the reaction between (A) and (B); component (F) comprising filler; and component (H) comprising at least one silane with at least two alkenyl groups per molecule, wherein said at least one silane is selected from the group consisting of compounds that can be represented by the general formula (III): wherein: R 1 and R 2 and n can be independently selected from each other; R 1 is a linear, branched or cyclic, monovalent, ethylenically unsaturated substituent which can undergo an addition reaction with SiH-groups and has 2 to 12 carbon atoms; R 2 is a monovalent radical without groups that can undergo an addition reaction with SiH-groups or have a detrimental influence on such a reaction; A is a bivalent, linear, branched or alicyclic, heterocyclic, aromatic or heteroaromatic group with 1 to 10,000 carbon atoms which can contain nitrogen or oxygen atoms; n is 2 or 3; and m is 2 or 3; wherein the consistency of the curable material according to ISO 4823 is greater than 35 mm; and with the proviso that the curable material does not comprise an added organopolysiloxane having a group with an ethylenically unsaturated double bond located at a non-terminal monomeric unit.
