Home - Products - Color Coated Aluminum - PVDF Color Coated Aluminum Coil
PVDF(fluorine-carbon) coating : made of fluorine carbon resin, pigment, ester solvent, after high temperature roasting and baking, the paint is solidified to dry film with super weather resistance. PVDF coating also can be classified as traditional PVDF and nanometer PVDF coating.
