<p>High reactivity polyurethane powder paints contain: (A) isocyanates at least partially capped with 1,2,4-triazole, comprising mixtures of (cyclo)aliphatic diisocyanate trimers (i.e. isocyanato-isocyanurates); (B) polymers with hydroxyl groups; and (C) optional standard auxiliary agents and additives. The use of these heat-curable, storage-stable, transparent and pigment-containing paints for coating substrates, preferably heat-sensitive work surfaces, is also claimed.</p> |
