Abstract

The present invention relates to a method which comprises mixing together an organosiloxane rubber, an organo-silicone cross-linking agent and a platinum catalyst. This method also comprises adding an additional catalyst in the shape of an inorganic cobalt compound having a cobalt content of 34 wt %. The organosiloxane rubber consists in α, φ-dihydroxypolydiorganosiloxanes of the general formula HO[R?1¨R?2¨SiO]¨n?H which have a viscosity of 15 300 P at 20 øC and a molecular weight of between 20000 and 65000. The letter n is an integer ranging from 270 to 870, while R?1¨ and R?2¨ represent aliphatic radicals comprising from 1 to 6 carbon atoms, phenyl, a chloromethyl group or a 3,3,3-trifluoropropyl group. The organo-silicone cross-linking agent consists in polyorganosiloxane hydrides of the general formula R?3¨¨3?SiO[R?4¨(H)SiO]¨m?[R?3¨¨2?SiO]¨l?SiR?3¨¨3? which have a SiH-group content of between 0.35 and 1.80 wt.% and a molecular weight of between 50 and 200. R?3¨ and R?4¨ represent an alkyl radical comprising from 1 to 6 carbon atoms and m is an integer ranging from 1 to 20 while l is an integer ranging from 0 to 19, with the proviso that m + l = 20. The components are mixed together according to the following proportions: 100 parts by weight of organosiloxane rubber; from 8 to 15 parts by weight of organo-silicone cross-linking agent; (9,04 8,94) 10?-4¨ parts by weight of platinum catalyst; and 12 22 parts by weight of additional catalyst.
