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.
