Thermosetting reactive systems

Abstract

Thermosetting reactive systems, comprising (a) at least one epoxide resin, (b) at least one isocyanate resin, (c) a reaction accelerator of the formula I ##STR1## in which R.sup.1 is --(CR.sup.4 R.sup.5).sub.n - with n=2-24, phenylene or naphthylene which is unsubstituted or mono- or poly-substituted by halogen, nitro, C.sub.1 -C.sub.4 -alkyl, C.sub.1-C.sub.4 alkoxy or C.sub.3 -C.sub.8 dialkylaminoalkyl, or a radical of the formulae ##STR2## R.sup.2 and R.sup.3 independently of one another are C.sub.1-C.sub.12 alkyl, phenyl or naphthyl which are unsubstituted or mono- or poly-substituted by halogen, nitro, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.1 -C.sub.4 alkoxy, or also C.sub.7 -C.sub.13 aralkyl, or in which R.sup.2 and R.sup.3, together with the N atom to which they are linked, form a 5-membered, 6-membered or 7-membered heterocyclic ring, and R.sup.4 and R.sup.5 independently of one another are hydrogen or C.sub.1 -C.sub.8 alkyl, and (d) if appropriate, a filler and/or further additives conventional in industry, have a long pot life and excellent heat-aging resistance.
