Abstract

A composition, suitable for the preparation of auto-adhering silicone rubber-coated materials (see Division B2), comprises a solution or dispersion in an organic solvent or diluent of a mixture of a vulcanisable organopolysiloxane and an alkylborate and/or alkenyl borate in amount to provide from 0.6 to 1.5% by weight of boron based on the weight of the siloxane. Borates specified are triethyl-, triallyl-, tributyl-and trihexyl-borates. The siloxanes may contain saturated, unsaturated or halogenated hydrocarbon or cyanoalkyl radicals and, if desired, a small proportion of Si-bonded hydroxyl, acetoxy or alkoxy radicals. The compositions may also contain fillers, e.g. diatomaceous earth, fume silica, titania, zirconia, zinc oxide and C black; vulcanizing agents, e.g. organic peroxides, preferably a mixture of two vulcanizing agents having vulcanizing temperatures of 20 DEG C. or more apart, e.g. a mixture of 2, 4-dichlorobenzoyl and dicumyl peroxides; hydrolysis retarders, e.g. metal alkoxides and Ti and Zr esters; and pigments, oxidation inhibitors, compression set additives and anti-structure additives. Solvents specified are toluene and benzene, and may contain from 2 to 15% by weight of ethanol or butanol. Examples are given. Specification 859,284 is referred to.ALSO:An auto-adhering, supported, organopolysiloxane-coated material is made by applying to a flexible substrate a solution or dispersion in an organic solvent or diluent of a composition comprising a mixture of a vulcanizable organopolysiloxane and an alkyl borate and/or alkenyl borate in amount to provide a boron content of from 0,6 to 1,5% by weight based on the weight of the siloxane (see Division C3), thereafter removing the solvent and at least partially vulcanizing the siloxane. The siloxane compositions may contain the customary fillers, additives and vulcanizing agents, though a mixture of two vulcanizing agents having vulcanizing temperatures of 20 DEG C. or more apart, is preferred. Solvents specified are toluene and benzene, and may contain from 2 to 15% of ethanol or butanol. The composition is applied to the supporting material as by dipping, spraying or brushing. If desired, the supporting material may first be coated with a silane, e.g. vinyl triethoxy silane. In the examples, glass cloth tapes are coated with the above siloxane compositions. Specification 859,284 is referred to.
