A heat-curable, epoxy-free coating composition comprises a dry blend of at least two different binder resins, each binder resin comprising of (a) a carboxyl-terminated polyester resin having an acid value from 20 to 200 mg KOH/g and a glass transition temperature of at least 40.degree. C., and (b) a .beta.-hydroxylalkylamide with at least two .beta.-hydroxylalkylamide groups per molecule; the at least two different binder resins differing in functionality, or in other words in the number of carboxyl and/or .beta.-hydroxylalkylamide groups per binder resin molecule. Along with the binder resins, the coating composition optionally includes further additives that are typical for the processing and use of powder coatings.
