POWDER COATING MATERIAL AND FLUORINE-CONTAINING LAMINATE

摘要

The present invention provides a powder coating composition free from hexavalent chromium to serve as a binder component but having an adhesion comparable to that of the primer based on chromium phosphate even if baked at elevated temperature for a long time. The present invention is a powder coating composition which contains a macromolecule compound (A) having amide group and/or imide group, an anti-oxidizing material (B) and a fluororesin (C), wherein an average particle size of the macromolecule compound (A) is smaller than 50 µm.
