Thermosetting reactive systems, comprising (a) at least one epoxide resin, (b) at least one isocyanate resin, (c) a reaction accelerator of the formula I <IMAGE> I in which R1 is -(CR4R5)n- with n=2-24, phenylene or naphthylene which is unsubstituted or mono- or poly-substituted by halogen, nitro, C1-C4-alkyl, C1-C4alkoxy or C3-C8dialkylaminoalkyl, or a radical of the formulae <IMAGE> <IMAGE> +TR <IMAGE> R2 and R3 independently of one another are C1-C12alkyl, phenyl or naphthyl which are unsubstituted or mono- or poly-substituted by halogen, nitro, C1-C4alkyl or C1-C1-C4alkoxy, or also C7-C13aralkyl, or in which R2 and R3, together with the N atom to which they are linked, form a 5-membered, 6-membered or 7-membered heterocyclic ring, and R4 and R5 independently of one another are hydrogen or C1-C8alkyl, and (d) if appropriate, a filler and/or further additives conventional in industry, have a long pot life and excellent heat-aging resistance. |
