The generation of electrostatic coating has solved the surface treatment of the aluminum plate of the curtain wall, which not only makes the color difference smaller, but also can obtain aluminum plates of multiple colors. Electrostatic powder coating: powder coating and fluorocarbon coating.

The raw materials for powder coating are: polyurethane, polyurethane resin, epoxy resin, hydroxy polyester resin and epoxy / polyester resin, which can be formulated in a variety of colors. The characteristics of powder coating: the coating equipment is manual, has automatic hanging type, simple construction, the coating thickness is more than 30 microns, impact resistance, abrasion resistance, corrosion resistance, weather resistance, etc., the coating price is better than fluorocarbon Cheap. The biggest weakness of powder spray is that it is afraid of sun ultraviolet radiation. Long-term exposure will cause natural fading and is generally used as an indoor accessory.

Another type of electrostatic powder coating is fluorocarbon coating, which is a high-end coating. Fluorocarbon coating has excellent resistance to fading, frosting, atmospheric pollution (acid rain, etc.), strong UV resistance, and crack resistance. As well as being able to withstand severe weather, it is generally used as an outdoor accessory.  

Chalco Aluminum offers the aluminum powder coating service with following textures and colors:
 
Gloss, Matte, Texture and Metallic. Orange, Red, Purple, Pink, Green, Blue, Brown, Tan and Yellow.

Design Considerations  

Mechanical finishing before powder coating is not usually required as the coating covers and smooth the surface. Powder coating typically adds 0.001″ – 0.003″ to each coated surface and slightly rounds edges. Textured and matte finishes hide scratches and abrasions better than gloss. Deep pockets and inside corners may not be coated due to the electrostatic process. Small amounts of powder may accumulate in holes, which may interfere with mating parts and threading. Plugging, redrilling or retapping can optionally be requested.
