| FENGHUI color coated aluminum coils |
FENGHUI color coated aluminum coils adopt the famous brandraw materials.It includes several classifications:
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 Color Coated Aluminum Coil:
FENGHUI PE color coated aluminum coil 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.The performance of PE color coated coil

PVDF(fluorine-carbon) Coating
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.
Parameters of PVDF Coating PVDF (KYNAR500 PVDF>70%)
| Substrates: | Aluminium (AA1100, 3003, 3004, 3105, 5006, 5052, 8011, etc), etc. |
| Thickness: | 0.08-1.5mm |
| Width: | ＜1800mm |
| Coils core diameter: | 150mm ,405mm, 505mm, 508mm, 510mm |
| Coating thickness: | PVDF >=25micron POLYESTER>=18micron |
| Color standard: | E < 2 or it is not obvious by eyeballing |
| Pencil hardness: | > 2HB |
| Coating adhesive: | not lower than first grade Impact: no any crack (50kg/cm, ASTMD-2794:1993) |
| Bend stength: | >100 times |
| Boiling point: | no any distortion and color change (in the 99 more or less 1 degree water, then cooling 2 hours) |
| Corrosive: | surface deep in the 5% muriatic acid and 5% NaCL, interior deepin the 2% muriatic acid and 2% NaCL, after 48 hours, no change |
