Types Of Color Coated Aluminum Coils

Color-coated aluminum coil coating is divided into: polyester coated aluminum coil (PE), fluorocarbon coated aluminum coil (PVDF). The solid film has protective decorative properties. It is a kind of anti-UV ultraviolet coating. The polyester resin uses the polymer containing ester bonds in the main chain as the monomer, and adds the alkyd resin. The ultraviolet absorber can be divided into matt and high-gloss series according to the gloss. It can give colorful aluminum products rich colors, and has good gloss and smoothness, as well as superior texture and feel, and can also increase the sense of hierarchy and three-dimensionality. It can protect objects exposed to the atmosphere and attacked by ultraviolet radiation, wind, rain, frost and snow; due to temperature difference, freeze-thaw cycles, corrosive gases and microorganisms, the coating can play a protective role. Especially suitable for interior decoration and advertising boards.

Fluorocarbon Coated Color Coated Aluminum Coil (PVDF)

Fluorocarbon coating is a coating of PVDF resin mainly referring to vinylidene fluoride homopolymer or copolymer of vinylidene fluoride and other small amount of fluorine-containing vinyl monomers. The chemical structure of the hydrofluoric acid base is combined with fluorine/carbon bonds. The stability and firmness of this chemical structure make the physical properties of fluorocarbon coatings different from general coatings. In addition to abrasion resistance and impact resistance in terms of mechanical properties, it has excellent properties, especially in harsh climates and environments, showing long-term fading resistance and UV resistance. After the film is formed by high temperature grilling, the molecular structure in 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 structure. In 1965, Pennwalt Chemical Company of the United States first applied fluorocarbon coatings to meet the indoor and outdoor aluminum coating of high-end buildings. A wide range of color choices, American solemn appearance, and durability have added brilliance to many magnificent curtain wall buildings around the world. Coating manufacturers’ guarantees for the service life of coatings started from 10 years, and developed from 15 years to more than 20 years. American research institutions have tested and compared fluorocarbon coatings, super coatings, and general coatings. The coated samples were exposed to hot sunlight in Florida, USA, and exposed to harsh environments with humid and salty air for 12 In 2018, it was actually proved that the stability and durability of fluorocarbon coatings were 30 and 80 percentage points higher than those of the other two coatings, and fluorocarbon coatings were guaranteed to be used in various harsh environments.

It is especially suitable for the decoration and display of indoor and outdoor decoration in public places, commercial chains, exhibition advertisements, etc.
