5 series Decorative Aluminum Alloy Sheet Color Coated Aluminum Coil

The color coated aluminum coil coating is divided into: polyester coated aluminum coil (PE), fluorocarbon coated aluminum coil (PVDF). The polyester coating formed by multiple baking coating on the surface of the aluminum plate can form a firm and continuous connection. The solid film has protective decorative properties. It is an anti-UV ultraviolet coating. The polyester resin uses a polymer containing an ester bond in the main chain as a monomer, and an alkyd resin is added. The ultraviolet absorber can be divided into a matt and a high-gloss series according to the gloss. It can give rich color to color aluminum products, and has good gloss and smoothness, as well as superior texture and hand feeling, and can also add layering and three-dimensionality. Protected objects are exposed to the atmosphere, exposed to ultraviolet light, wind, rain, frost and snow; the coating can protect due to temperature differences, freeze-thaw cycles, corrosive gases and microorganisms. Especially suitable for interior decoration and advertising panels.

The fluorocarbon coating is a coating of PVDF resin mainly referring to a vinylidene fluoride homopolymer or a copolymer of vinylidene fluoride and other small amount of fluorine-containing vinyl monomer. The chemical structure of the fluoric acid base is combined by a fluorine/carbon bond. This chemical structural stability and firmness make the physical properties of fluorocarbon coatings different from conventional coatings. In addition to the abrasion resistance in terms of mechanical properties, impact resistance has excellent performance, especially in harsh weather and environment, showing long-lasting resistance to fading and UV. After the high temperature barbecue is formed into a film, the molecular structure in the coating is tight and has excellent weather resistance. Fluorocarbon coatings can be classified into conventional fluorocarbon and nano fluorocarbon coatings according to the surface film formation structure. In 1965, the US Pennwalt Chemical Company firstly used fluorocarbon coatings to meet the indoor and outdoor aluminum coatings of high-end buildings. The choice of a wide range of colors, the solemn appearance of the United States, and durability added brilliance to many magnificent curtain wall buildings around the world. The coating manufacturer's guarantee of the service life of the coating began to be 10 years and 15 years and can be guaranteed for more than 20 years. American research institutes have tested and compared fluorocarbon coatings and super-coatings and general coatings. The coated samples were placed in hot sunlight in Florida, USA, and exposed to the harsh environment of humid salty air. In the year, it was proved that the stability and durability of fluorocarbon coatings were 30 and 80% higher than those of the other two coatings, and fluorocarbon coatings were guaranteed to be used in various harsh environments.

There is no composite high temperature indentation on the surface. There is no residual stress on the plate surface and no deformation after shearing.It is resistant to salt and alkali acid rain, and it will not corrode and produce germs. It will not release any toxic gas, and will not cause corrosion of keel and fixing parts, and flame retardancy. According to national regulations, it is not lower than B1.
