The praying is a common method of coating aluminum plates with visible coating colors, while electrostatic spraying has two types: powder spraying and fluorocarbon spraying. Powder-coated aluminum sheet is processed powder with low cost, raw materials for curtain wall applications are sprayed with powder-coated polyurethane, polyurethane resin, epoxy resin, hydroxy polyester resin and epoxy / polyester resin, which can be in various colors To prepare.

The characteristics of powder-coated aluminum are: the spraying equipment has manual and automatic suspension, the coating thickness is greater than 30 microns, the powder-coated aluminum plate and coil has impact resistance, wear resistance, corrosion resistance, weather resistance, etc., and the coating Prices are lower than fluorocarbons. The powder-coated aluminum cannot withstand the sun's ultraviolet radiation like the fluorocarbon coating. After long-term exposure, the surface will cause natural discoloration.

Another type of electrostatic spraying is liquid spraying, also known as fluorocarbon spraying. It belongs to high-grade spraying and has a higher price. Fluorocarbon-coated aluminum plates have been widely used in aluminum curtain walls. Due to its outstanding characteristics, it has been increasingly valued and favored by the construction industry and users. The aluminum plate coated with fluorocarbon color has excellent resistance to fading, frost, air pollution (acid rain, etc.), strong UV resistance, crack resistance and ability to withstand severe weather conditions.
