Beschreibung
Zusammenfassung:	UV- and heat-curable aqueous polyurethane dispersions comprise compounds attached via polyisocyanates and containing UV-polymerizable C=C double bonds, aliphatic diols incorporated by way of isocyanates and having a molecular weight of less than 500 g/mol, compounds attached via isocyanates and containing carboxylic acid or sulfonic acid groups and/or salts thereof, free hydroxyl groups, and compounds containing blocked isocyanate groups. They are suitable for coating heat-stable substrates such as metal substrates and may be used with advantage for automotive clearcoats.
