Abstract
1528974 Solventless silicone resins DOW CORNING CORP 18 Nov 1975 [4 Aug 1975] 47425/75 Heading C3T A curable solventless resinous composition comprises a mixture of (A) a copolymer of, in mole per cent, 35-42 monophenylsiloxane units, 0-12 diphenylsiloxane units, 35-50 dimethylsiloxane units and 8-15 vinylmethylsiloxane units, and (B) a copolymer of, in mole per cent, 8-15 diphenylsiloxane units, 30-55 methylhydrogen siloxane units, 28-45 dimethylsiloxane units and 5-12 trimethylsiloxane units, the amounts being such that there is a substantially stoichiometric amount of SiH and Si vinyl Œ 10% of either ingredient. The composition may be cured by heating in the presence of a Pt catalyst, e.g. Pt dispersed on charcoal, chloroplatinic acid, complexes of Pt or chloroplatinic acid with olefins or unsaturated organosilicon compounds or platinumsulphur complexes. The composition may comprise fillers, e.g. glass fibres and finely divided crystalline silica. A preferred composition comprises 35-65% wt. of components (A) plus (B), 5-25% wt. of glass fibres having an average length of from 0À08 to 0À32 cm. and from 10-50% wt. of crystalline silica having an average particle size of from 2-8 microns. Resins (A) and (B) may be made by the cohydrolysis followed by condensation of the corresponding chlorosilanes. The cured compositions have improved thermal shock resistance. Uses.-Encapsulating electrical and electronic devices; coating compositions.
