Color coated aluminum roll

Pingyin Chengye Colorful PaintingAluminum coil manufacturer-Color coated aluminum, as the name suggests, refers to the surface coating and coloring treatment of aluminum plates. The common type is fluorocarbon color coated aluminum, which is widely used in aluminum plastic plates, aluminum ceilings, cans, and electronic products.

Color coated aluminum rollThe coating is divided into: polyester coated aluminum roll (PE) and fluorocarbon coated aluminum roll (PVDF) The polyester coating formed by repeatedly baking and coating the surface of the aluminum plate can form a firmly attached continuous solid film with protective and decorative properties. It is a type of UV resistant coating, and polyester resin uses polymer containing ester bonds in the main chain as monomers, with alkyd resin added. UV absorbers can be divided into matte and high gloss series based on glossiness. It can endow colorful aluminum products with rich colors, good glossiness and smoothness, superior texture and hand feel, and can also increase the sense of layering and three-dimensional feeling. It can protect objects from being exposed to the atmosphere and being attacked by ultraviolet radiation, wind, rain, frost, and snow; Due to temperature differences, freeze-thaw cycles, corrosive gases, and microbial effects, coatings can provide protection. Especially suitable for indoor decoration and advertising boards.

Fluorocarbon coated aluminum foil (PVDF)

Fluorocarbon coatings refer to PVDF resins, which mainly refer to coatings made of homopolymers of vinylidene fluoride or copolymers of vinylidene fluoride and other small amounts of fluorinated vinyl monomers. The chemical structure of fluoric acid based materials is bonded by fluorine/carbonization bonds. The stability and firmness of this chemical structure make the physical properties of fluorocarbon coatings different from ordinary coatings. In addition to excellent wear resistance and impact resistance in terms of mechanical properties, it also exhibits long-lasting fading resistance and UV resistance, especially in harsh climates and environments. After high-temperature barbecue and film formation, the molecular structure of the coating is tight and has strong weather resistance. Fluorocarbon coatings can be divided into two types based on their surface film-forming structure: traditional fluorocarbon coatings and nano fluorocarbon coatings. In 1965, Pennwalt Chemical Company in the United States first introduced fluorocarbon coatings to meet the coating requirements of high-end indoor and outdoor aluminum materials in buildings. The wide selection of colors, the dignified appearance of the United States, and durability added luster to many magnificent curtain wall buildings around the world. The coating manufacturer's guarantee for the service life of the coating starts from 10 years and develops from 15 years to over 20 years. Research institutions in the United States have tested and compared fluorocarbon coatings, super coatings, and general coatings. Samples of the coatings were placed in hot sunlight in Florida, USA, and exposed to harsh environments containing moisture and salt for 12 years. It has been proven that the stability and durability of fluorocarbon coatings are 30 and 80 percentage points higher than the other two coatings. Fluorocarbon coatings ensure their use in various harsh environments.

Especially suitable for indoor and outdoor decoration in public places, decoration and display of commercial chains, exhibition advertisements, etc.
