Annealing treatment can improve its plasticity, quenching can improve its hardness and strength. Data source: GB/T 6892-2015.

Advanced Color-Coated Process

Polyester-coated pre-coating Technology(PE)

Polyester coating is a kind of anti-UV UV polyester resin coating, its main component is using polymer containing ester bonds in the main chain as a monomer, adding alkyd resin, and ultraviolet absorber. After baking polyester coating on the surface of aluminum (aluminum sheet, aluminum roll) many times, it forms a solid film with protection and decoration. The polyester coating protects color-coated aluminum products (aluminum sheets, aluminum rolls) from exposure to the atmosphere due to temperature differences, freeze-thaw cycles, corrosive gases and microorganisms, and from ultraviolet radiation, wind, rain, frost, and snow.

In addition, the polyester coating can give color-coated aluminum substrate products rich color, according to gloss polyester coating can be divided into matte and highlight series. Therefore, the color-coated aluminum coil not only has good gloss and smoothness, but also has superior texture and feel, and can also increase the sense of layer and three-dimensional. It is especially suitable for interior decoration and advertising boards.

polyvinylidene difluoride coating technology(PVDF)

Fluorocarbon coating is PVDF resin, mainly refers to vinylidene fluoride homopolymer or vinylidene fluoride and other small amounts of fluorinated vinyl monomer copolymer coatings. The fluoric acid-base material with fluorine/carbonization bond has a stable and firm chemical structure, which makes the physical properties of fluorocarbon coatings different from those of general coatings.

Fluorocarbon coatings can be divided into traditional fluorocarbon coatings and nano-fluorocarbon coatings according to the film formation structure of the surface. In 1965, the Pennwalt Chemical Company of the United States for the first time used fluorocarbon paint for the coating of indoor and outdoor aluminum in high-grade buildings, a wide range of color selectivity, solemn appearance, and durability for many magnificent curtain wall buildings around the world added luster. In addition to the wear and impact resistance in terms of mechanical properties, it also shows excellent and long-term fading resistance and UV resistance in harsh climates and humid environments. After high-temperature grilling, the molecular structure of the coating is tight, and the machine has superior weather resistance. The coating manufacturer’s guarantee of the service life of the coating began to be 10 years, 15 years to guarantee more than 20 years.

American research institutions have tested and compared fluorocarbon coatings super coatings and general coatings. The samples of the coatings were exposed to hot sunlight in Florida, the United States, and exposed to the harsh environment of humid salty air for 12 years, which proves that the stability and durability of fluorocarbon coatings are 30%-80% higher than those of the other two coatings. Fluorocarbon coatings ensure that they can be used in various harsh environments. It is especially suitable for indoor and outdoor decoration in public places, commercial chains, exhibition advertising, and other decorations and displays.
