The painted aluminum trim coil are packaged in rolls, so they can also be called color coated aluminum trim coils. The surface of the painted aluminum coil is treated with fluorocarbon coloring and special processes, such as metal drawing, engraving patterns, etc., have a very decorative effect. So the aluminum trim coil color coated is widely recognized by modern families.
Color painted aluminum trim coil for decoration are widely used because they have the characteristics of good strength, corrosion resistance, long life, easy molding, easy cleaning, no discoloration and no pollution. The color coated aluminum trim coil are currently the most popular new building material. It is widely used in aluminum composite panels, aluminum veneers, aluminum honeycomb panels, aluminum ceilings, roof surfaces, scraps, cans and electronic products. The performance of the color coated aluminum coil is very stable and not easy to be corroded. The surface layer can be guaranteed for 30 years after special treatment. The weight per unit volume is the lightest among the metal materials.
The painted aluminum trim coil mainly have 1100, 3003, 3004, 3104, 3105 and 5052 aluminium alloy, and the roofing system is the biggest application. Fluorocarbon aluminum-magnesium-manganese plates should be anodized on the surface or other effective surface treatments. The thickness and material of the surface treatment layer should comply with the relevant regulations of the current industry standards. The surface of the painted aluminum coil is treated with fluorocarbon resin, and the content of fluorocarbon resin should not be less than 75%. Three to four layers of fluorocarbon resin coating can be used in the seaside and areas with severe acid rain, and the thickness should be greater than 40μm. in other areas, two can be used, the thickness of Dow fluorocarbon resin coating should be greater than 25μm.
