The main raw material of white powder coated aluminium is aluminum sheet, which needs to be 3003 H24, 1100 H24, or 5005 H24 anti-rust aluminum sheet, and the thickness can be 0.18- 1.5mm. The RAL code of powder coated white aluminum are ral 9006, ral 9007, ral 9008 and so on. The powder coating of white aluminum sheet are PE and PVDF paint, after powder coated, the white painted aluminum sheet are mainly applied to the roofing and wall of buildings. The paint needs to use high weather-resistant exterior paint to ensure that it will not fade or age for 15 years. It is used on the roof and is generally sprayed with weather-resistant paint as a protection for the aluminum surface to resist the external natural attack and strong light exposure.
The spraying technology of white powder coated aluminium is a professional spraying production line. The spraying is a process of pre-treatment, color spraying, and then high-temperature curing. The conventional specifications and dimensions of powder coated aluminum sheet are as follows, and other specifications and dimensions can also be negotiated by both parties.
Alloy: 1100 H24, 3003 H24, 5005 H24
Thickness: 0.18-1.5 mm
Length: 2000, 2440, 3000, 3200, etc., in mm.
Width: 1220, 1250, 1500, etc., in mm.
The size of the special-shaped plate can be negotiated by both parties.
Type of coating: Polyester powder coating, fluorocarbon powder coating, stone grain powder coating, wooden grain powder coating, etc.
The white powder coated aluminium with PVDF paint has better performance, for bright colors, PVDF powder coating is necessary. Fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, excellent cold and heat resistance, can resist strong ultraviolet radiation, and can maintain long-term non-fading and non-pulverizing ,long lasting.
