Powder coating compositions for the production of low-gloss coatings

摘要: Disclosed are powder coating compositions comprised of one or more semi-crystalline polyesters, hydroxyl acrylic polymers and a blocked polyisocyanate cross-linking agent. Coatings the on shaped metal articles exhibit an ASTM D-523-85 60° gloss value not greater than 35, D-2794-84 front/back impact strength values at least 40/20 inch-pounds D-3359-83 cross-hatch adhesion pass percent 90.
