ABSTRACT:
A powder coating composition which is curable at 120.degree. to 150.degree. C. and contains A) one or more copolymers prepared from olefinically unsaturated monomers and containing epoxy groups and optionally hydroxyl groups, B) one or more curing agents containing carboxylic acid or carboxylic acid anhydride groups, and C) one or more polyaddition compounds which contain uretdione groups, have a melting point or range of 40.degree. C. to 120.degree. C. and are prepared from (cyclo)aliphatic diisocyanates; and its use for coating of heat-resistant substrates, especially automotive substrates.
