COATING TYPES
POLY VINYLIDENE DIFLUORIDE (PVDF) COATING
A Highly non-reactive thermoplastic fluoropolymer produced by the polymerrization of vinylidene difluoride.
(Warranty 10 years, back to back with KYNAR/HYLAR).
FEVE ALUMINUM COMPOSITE PANEL COATING
Feve aluminum composite panel is a combination of the
advantages of PE coating and PVDF Coating aluminum composite materials. For instance, its glossy and color brightness is the same as PE coating ACP and its weather resistance is comparable with that of PVDF coating aluminum composite panel.
