Abstract (en)
1. Powdery coating products with high storage stability and a grain size smaller than 0,25 mm, preferably between 0,02 and 0,06 mm, based upon 1,2-epoxide compounds with more than one 1,2-epoxide group in the molecule and a lower fusion point > 40 degrees C, hardening agents and customary lacquer additives, characterised in that the coating product contains as hardening agent polyisocyanates blocked with cyclic amidines of the general formula see diagramm : EP0000971,P29,F1 wherein a means 1 or 2, R means same or different substituents selected from the group of hydrogen, alkyl, cycloalkyl, aralkyl, and aryl radical, and if necessary, 2 geminal or vicinal R's together are substituents of an unsubstituted or alkylsubstituted cycloalkyl ring, whereby the hardening agent in the coating product amounting to 2-15 wt.% with respect to the quantity of solid 1,2-epoxide compound.
