EPOXIDIC CASTING PASTE WITH INCREASED STABILITY AT THERMAL DEGRADATION

摘要

the present invention refers to a mass of epoxy casting with increased stability to thermal degradation.on the basis of the type of epoxy resin having epoxy equivalent of diglicidileter bisfenolului e = 180...194 g, with fenolformaldehidica type novolac resin with molecular weight 700...1000 g and g is equivalent hidroxilic = 107 and added fix aminic, constituted of 80 95 g epoxy resin, novolac type resin 5 20 g, 180...220 g dry quartz flour, in advance, 16 h, 130...140 degree c, with granulatia gripped between 5 and 100 mum, and a content of sio 2 and index over 98.5% under 0.5% fe index 2 an index 3 to add 3...5% of the mixture of rasini, n, n, - dimetilbenzilamina.
