Room temperature-stable blends of heat-curable reactive resins, latent catalyst complexes for these blends, process for their manufacture and the heat-curable resins obtained from these blends

摘要

stable mixture at room temperature reactive resins thermoset cissables hot materials for insulation impregnation electri cal or for the preparation of molding products or composite materials, comprising liquid oligo- or polyisocyanates compounds and liquid epoxy resins and a catalyst ment cured latent, inactive at room temperature, consisting of an addition complex of an amine compound of the group consisting of amines, alkylhydrazines and imidazoles, with a boron halide. They further comprise a small quantié maleic anhydride, or the boron halide is boron tribromide without addition of maleic anhydride. Complex latent catalysts of these mixtures formed by the addition of BBr₃ complex and an amine, an alkyl hydrazine or an imidazole. Manufacturing processes and resins obtained from these mixtures.
