Title: Thermal curable powder coating composition

Abstract: A powder coating composition comprising (A) at least one hydroxyl functional polyurethane resin binder, and (B) at least one polyurethane resin as cross-linking agent containing blocked isocyanate groups, wherein the at least one hydroxyl functional polyurethane resin binder (A) and the at least one polyurethane resin (B) both having a melting temperature of 60 to 180.degree. C., in particular, 80 to 160.degree. C.; the powder coating composition makes it possible to achieve a low melt viscosity and an excellent processability along with a good storage stability and in particular, to form thin films of the coating layers having high flexibility in combination with an excellent weather resistance.
