Abstract

The use of pulverulent thermosetting coating compositions based on physical mixtures of individual isocyanato isocyanurates formed from aliphatic and (cyclo)aliphatic and/or cycloaliphatic diisocyanates and from polyesters containing hydroxyl groups and terephthalic acid for coil powder coating materials, to a process for producing such coatings, and to the metal coils coated with such coating materials.
