PVDF Color Coated Aluminum Coil
PVDF Color Coated Aluminum Coil :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.
A．Traditional PVDF Coating, with KYNAR500 PVDF, two or three times for
coating and baking, has good properties of anti-acid, anti-alkali and is
durable in atrocious weather and environment, keeping 15 years no
unwonted fading. In view of these facts, we recommend this panel applied
for external wall cladding.
B．Nanometer PVDF Coating, which different with traditional PVDF is the
clear coating. It contains nanometer element, which can protect panel
from pollution, Because nanometer has self-cleaning effect, It easy to
get rid of dust and pollution by raining or water.
