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.
