Abstract
An elastomer-forming composition comprises, by weight, 1 pt. of an organosiloxane having from 1,98 to 2,01 organic radicals per Si atom, and a molecular weight of not less than 3 x 105, 1,5 to 3 pts. of a semi- or non-reinforcing filler, 0,02 to 0,2 pts. of a fluorohydrocarbon polymer, and 0,01 to 0,15 pts. of a structure control additive. The siloxanes may contain alkyl, alkenyl or aryl radicals. Fillers specified are diatomaceous earth, clays, synthetic silicas, titania and zirconium silicate. Fluorinated polymers specified are polytrifluorochloroethylene and polytetrafluoroethylene. Structure control additives specified are certain glycols and silanes described in Specifications 792,580 and 800,554, diphenylsilanediol, diphenyldimethoxysilane and diphenyldiethoxysilane. Examples disclose compositions of (1) methylvinylpolysiloxane, silica of average particle size 40 m m , P.T.F.E., red iron oxide, diphenyldimethoxysilane and 2 : 4-dichlorobenzoyl peroxide/silicone liquid paste; and (2) dimethylpolysiloxane, silica of average particle size 40 m m , P.T.F.E., benzoyl peroxide/silicone liquid paste, and (tetramethylenedioxy)-dimethylsilane. Specification 802,957 also is referred to.
