Epoxy resin, polyamine hardener and N,N′,N″-tris(dialkylaminoalkyl)hexahydrotriazine

The invention relates to curable mixtures of glycidyl compounds and aminic hardeners, which comprise heterocyclic tertiary amines as cure accelerators and which, while having a long potlife, still have a rapid full cure rate. The invention relates to curable mixtures based on epoxy resins and aminic hardeners and cure accelerators, and, optionally solvents, plasticisers, UV stabilisers, dyes, pigments and/or fillers, wherein there is used as cure accelerator from 1 to 20% by weight, based on epoxy resin, of at least one heterocyclic compound of the general formula (I) wherein R, Rand R, which may be the same or different, areradicals in which a=2 or 3 and b=0 or 1.
