PVDF Color Coated Aluminum Coil

  • Front coating thickness requirements: primer 5 microns, top paint 20-22 microns.
  • Back coating thickness recommended: primer 5 microns, top paint 5 microns.
  • Color: Color can be customized and matched according to user requirements. Part of the colors need to be replaced similarly due to weather resistance demand.
  • Gloss: Standard  25+1-5.
