Abstract
The invention comprises a thermosetting powder coating composition comprising first and second resin, the first resin being an acid functional polyester resin with an acid value below 50 mg KOH/g, the second resin being obtainable by reacting hydroxyl functional components and acid functional components, the hydroxyl functional components containing 2 hydroxyl functional groups per molecule and/or at least 3 hydroxyl functional groups per molecule, the acid functional components containing 2 acid functional groups per molecule and/or at least 3 acid functional groups per molecule, wherein more than 90 mol. % of the total of hydroxyl functional components in the second resin originate from neopentyl glycol (NPG), and from 6 to 11 mol % of the total of hydroxyl functional components and acid functional components in the second resin originating from hydroxyl functional components and/or acid functional components having at least 3 functional groups per molecule.
