Abstract

Procedure for the coating of metal tubes, with a hard-plastic protective layer by application of powder lacquers of cyclic amidines and epoxide compounds, with more than one group of 1,2-epoxide in the molecule, as well as the usual additions and hardening of the powder layer at elevated temperature, characterized in that the powder coating is electrostatically applied on the metal tubes heated at 200-300ºC and the coating is hardened by the thermal capacity of the tubes without supply of further thermal energy, and because it is used as cyclic amidines, imidazoline derivatives of the general formula ** (see formula) ** Wherein r is hydrogen, an alkyl or aryl moiety, r 'a cycloalkyl or heterocycloalkyl moiety or a moiety r, r "is an alkylene moiety or an arylene moiety optionally alkyl or substituted aryl and x is hydrogen or a rest of ** (see formula) ** And the 1,2-epoxide compounds possess an initial lower melting point higher than 60º c.
