Disclosed is a low-temperature-curable, solid polyurethane powder coating composition comprising A) at least one uretdione-containing powder coating hardener based on an aliphatic, (cyclo)aliphatic or cycloaliphatic polyisocyanate and a hydroxyl-containing compound, having a melting point of from 40 to 130°C, a free NCO content of less than 5% by weight, and a uretdione content of. 6-18% by weight, B) at least one hydroxyl-containing polymer having a melting point of from 40 to 130°C, and an OH number of between 20 and 200 mg KOH/gram, C) at least one catalyst of the formula M(OR1)n(OR2)m(OR3)o(OR4)p(OR5)q(OR6)r, in which M is a metal in a positive oxidation state that is the sum of n+m+o+p+q+r; m, n, o, p, q and r are each an integer of 0 to 6 and the sum is 1 to 6; R1 - R6 are each hydrogen, alkyl, aryl, aralkyl, heteroaryl or alkoxyalkyl. The powder coating composition can be cured at a low temperature, e.g., 120-180°C.
