PE(polyester) coating:high molecular polymer as monomer and addition of alkyd, is an UV-resistant coating. It can be classified matt and glossy according to coating gloss. The compact molecule structure, makes paint surface luster and smooth,which assure good printing on the panel surface. With an warranty of 8-10 years for weather resistance, it is specially applied for internal decoration and sign board.
PE COATED COILS with good PE Paints and high performance of aluminum coil is produced by advanced roller coating. All performance parameters are up to or much higher than related national standards.

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.
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.
