Front Face:HAOMEI pre-painted aluminium coil for roof has been coil coated with a PVDF paint system (80/20). The paint thickness is approx. 25µm for a two layer paint system. For special coatings the paint thickness is approx. 40 µm.
Reverse side:The reverse side of HAOMEI is provided with a transparent protective lacquer, thickness approx. 3µm. This protective lacquer is suitable for gluing and foaming. Transparent protective lacquer with HAOMEI symbol.
Protective film:HAOMEI is delivered with a patented, asymmetrically perforated anti-slip protective film for the front side. This protection film is UV-resistant and can remain on the panels for up to six months until all work is complete.
HAOMEI prepaited aluinum for roofing have the Function--cost-effective and easy to work, the alloy, coating and elasticity of HAOMEI prepainted aluinum has been specially geared for working in plumbing technology, The prepainted is therefore ideal for lock-welt technologies such as double lock-welt or ledge roof technologies, but can also be cut, sawn, folded, drilled or riveted without problem using standard machines--and without the coating chipping or cracking.

The PVDF coating features good shaping properties and outstanding resistance to weather conditions.
The PVDF coating comes in a 80/20 quality(80%PVDF+20% acrylate) which is used for HAOMEI, and a PVDF coating in 70/30(70%PVDF+30% acrylate). Generally speaking, the higher the PVDF content, the better the resistance to weathering and annual erosion. In general term, the higher the PVDF content, the better resistance to weathering.
This means that the groundwater is not contaminated, the pigment used are normally non-hazardous, in some cases they are even safe for use with foodstuffs. The processing for producting the pre painted aluminum for roofing:
There are kind of colors to choose from including metallic and special finishes.
