The color painted aluminum sheet is a composite material in which an aluminum sheet substrate is coated with one or more layers of organic paint on a surface. The painted aluminium sheet is processed after being subjected to a color coating unit and baked and cured. The color coated aluminum sheet has the advantages of both aluminum sheet and organic material, and has the advantages of high mechanical strength, good toughness, easy processing and the like, and good coloring, decoration and corrosion resistance of the organic polymer coating material. It can be easily processed by punching, bending, deep drawing, welding, etc.

The painted aluminum sheet coil products are practical, decorative, easy to process and durable. So the aluminium painted sheet is widely used in industrial buildings, stations, airports, stadiums, commercial buildings, residential buildings and other building and home appliance manufacturing industries. The color coated aluminum coils are made of polyester coated aluminum coil (PE) and fluorocarbon coated aluminum coil (PVDF). Polyester coated aluminum coil sheet is an anti-UV UV coating, and the polyester resin is used in the main chain. The polymer containing the ester bond is a monomer, and an alkyd resin is added. The ultraviolet absorber can be divided into a matt and a high light series according to the gloss. Especially suitable for interior decoration and advertising panels. The fluorocarbon painted aluminum sheet coil is a fluorocarbon resin, a pigment, an alcohol ester solvent and an auxiliary agent, which are fluoroenyne as a basic monomer. After the high temperature barbecue is formed into a film, the molecular structure in the coating is tight and has excellent weather resistance.
