Abstract

A curing agent for the production of low gloss powder coatings based on epoxy resins consists essentially of a mixture of the components a) 2-imidazoline derivative having a melting point of >60.degree. C. and b) cyanuric acid as well as, if desired, anticaking agents or/and stabilizers. The low gloss powder coatings produced with these curing agents have the desired low degrees of gloss and good adhesive strengths, they form smooth and uniform surfaces and show no signs of yellowing even after long stoving times.
