description | A thermosetting powder coating composition comprising a binder, wherein 100 parts by weight of the binder comprises (A) from 30 to 70 parts by weight of at least one carboxylic acid functional branched polyester having an acid number of at least 77 mg KOH/g, and (B) from 70 to 30 parts by weight of at least one carboxylic acid functional polyester having an acid number of lower than 50 mg KOH/g. The thermosetting powder composition may be used for coating metallic and non-metallic substrates, it provides outstanding flow and permits to obtain low gloss coatings, provides excellent mechanical properties, and exhibits good solvent resistance and weathering. |
