Color Coating Aluminium Coil classification

The coating of Color Coating Aluminium Coil is divided into polyester-coated aluminum coils (PE) and fluorocarbon-coated aluminum coils (PVDF). The polyester coating formed by baking the surface of the aluminum coil many times can form solidly adhered continuous Solid films that have protective decorative properties. It is an anti-UV coating. The polyester resin is made of a high molecular polymer containing ester bonds in the main chain, and an alkyd resin is added. The ultraviolet absorber can be divided into matt and high-gloss series according to the gloss. It can endow colorful aluminum products with rich colors, good gloss, smoothness, superior texture and feel, and increase the sense of layering and three-dimensionality. It can protect objects exposed to the atmosphere and be attacked by ultraviolet radiation, wind, rain, frost, and snow; due to temperature differences, freeze-thaw cycles, corrosive gases, and microorganisms, the coating can play a protective role. Especially suitable for interior decoration and advertising boards.
Fluorocarbon Coated Prepainted Aluminum Coil (PVDF)
Fluorocarbon coatings are PVDF resins, mainly referring to vinylidene fluoride homopolymers or copolymers of vinylidene fluoride and other small amounts of fluorine-containing vinyl monomers. Fluorine/carbon bonds bond the chemical structure of the hydrofluoric acid base material. The stability and firmness of this chemical structure make the physical properties of fluorocarbon coatings different from ordinary coatings. In addition to the abrasion resistance and impact resistance in terms of mechanical properties, it has excellent performance, especially in harsh climates and environments, and it shows long-term fading resistance and UV resistance. After high-temperature baking to form a film, the molecular structure of the coating is tight and has super weather resistance. Fluorocarbon coatings can be divided into traditional fluorocarbon coatings and nano-fluorocarbon coatings according to the surface film formation structure. In 1965, Pennwalt Chemical Company of the United States first used fluorocarbon coatings to meet the needs of coating indoor and outdoor aluminum materials in high-end buildings. The wide choice of colors, the solemn appearance of the United States, and its durability have added luster to many magnificent curtain wall buildings around the world. Coating manufacturers guarantee the service life of coatings from 10 years, 15 years, to more than 20 years. American research institutions have tested and compared fluorocarbon, super, and general coatings. The samples of the respective coatings were exposed to hot sunlight in Florida, USA, and exposed to the harsh environment of humid and salty air for 12 years. In 2010, it was proved that the stability and durability of fluorocarbon coatings were 30 and 80 percent higher than the other two coatings, and fluorocarbon coatings ensured their use in various harsh environments.
