PVDF Coated aluminum aluminium sheets coils
Specification of PVDF Coated
1. Aluminum coated coil alloy: AA1100,AA1050, AA3003, AA3004, AA3005, AA3105, AA5005, AA5182, AA5052, AA5754, AA5454, AA8011
2. Temper: O/H42/H44/H46/H48
3. Aluminum thickness (gauges): 0.02mm to 3.0mm
4. PVDF pre-painted aluminum coil width: 10mm to 1800mm
5 Coating: polyvinylidene difluoride (PVDF), no less than 25 micron for two times coating, three times coating 32micron.
6. Available colors: solid, metallic, marble, wood, anti-static, anti-scratch, etc
7. Coating hardness (pencil hardness): more than 2HB
8. Impact resistance: no cracking or peeling
9. Flexibility (T-bend): 2T
10. MEK resistance: more than 100 times
11. Further Processing: embossing, cutting to solid aluminium sheets, slitting to aluminium strips, etc
PVDF coating: 30 years guarantee
Three Coating Options
1. Self-clean Namo coating
With Namotechnology, our Namo PVDF coating could make it clean itself using sun and rain, maintenance and cleaning cost are reduced by at least 50%.
2. Durable coating
With our high-performance coating based on polymer resin, resistant to UV rays, moisture and abrasion. With such coating we can guarantee of up to 20 years.
3. Gloss coating
We have 3 gloss levels coating are available: High gloss, satin and matt.
PVDF Coating Compostion
To meet the industry's highest performance standards for architectural aluminum products, 70% PVDF resin-based coatings are recommended. The remaining 30% of the binder is composed of acrylic. Pigments, solvents and additives are also included in the formulated liquid product.
Polyvinylidene difluoride (PVDF)Painted Aluminum Coil applications:
From the roof to front door, PVDF resin-based coating protect and enhance numerous architectural aluminum products.
End-use include:
Aluminium roofing and wall panel systems.
Framing for curtainwall, windows, skylights and entrance systems
Louvers and grills, soffits, fascia, mullions, column covers and more.
