Room-temperature-curing silicone rubber compositions

Claim 1

Room-temperature-curing silicone rubber composition consisting essentially of (a) 100 parts by weight of an organopolysiloxane having a viscosity of 0.1 to 100 Pa•s at 25° C., having the general formula ##STR4## wherein X is a hydroxyl group or a hydrolyzable group, R is a monovalent hydrocarbon radical having 1-18 carbon atoms or a cyanoalkyl group, n is 1, 2 or 3, y has an average value between 1.90 and 2.05, m has an average value between 0.95 and 1.10, y+ m is equal to 3, l is a positive integer and the total number of X groups in the molecule is at least 3, (b) 0-150 parts by weight of a filler selected from a group consisting of silica and titanium dioxide, or mixtures thereof, (c) 3-200 parts per million parts of component (a), of platinum or an equivalent amount of platinum from a platinum compound, (d) 0.05-60 parts by weight carbon black, (e) 0.1-1.5 parts by weight of a triazole, (f) 0.6 parts by weight of a curing catalyst, and (g) 0.5-20 parts by weight of a silicon containing crosslinker which crosslinker has at least 3 Si-bonded hydrolyzable groups, wherein the sum of the weight of components (b)+ (d) in the rubber composition must be 5 parts by weight or greater.
