A method of producing coatings on the basis of two-component systems composed of 1,2-epoxy compounds having at least one 1,2-epoxy group in the molecule, plus cyclic amidines and the conventional paint additives, which are thermosetting at 100 DEG to 200 DEG C, the said method being characterized in that one uses as cyclic amidines imidazoline or tetrahydropyrimidine derivatives of the general formula <IMAGE> IN WHICH N EQUALS 2 OR 3; M EQUALS 1 OR 2; R1, R2 and R3 are identical or different, and represent hydrogen, alkyl, aryl, aralkyl, cycloalkyl, heterocyclics, ether, theoether, halogen, -N(R)2, nitro groups, keto groups, ester groups or carbonamide groups, and R represents alkyl, alkylene, an aryl, aralkyl, cycloalkyl or heterocyclic radical, substituted if desired with halogen, nitro groups, alkyl groups, alkoxy groups or amino groups, and, when m equals 1, represents also hydrogen, a plurality of radicals being able to be joined, also by hetero atoms such as O, N or S, if desired.
