1 What is color coated aluminum coil?
Color coated aluminum coil: As the name suggests is to paint the surface of aluminum coil, include PVDF color coated aluminum coil, PE color coated aluminum coil, widely used in aluminum-plastic board, metal roof panels , metal wall panels, aluminum louver, aluminum composite board, aluminum ceiling, cans, electronic products and other industries
2 How are color coated aluminum coils classified?
According to the coating can be divided into polyester coated aluminum coil (PE), fluorocarbon coated aluminum coil (PVDF).
The polyester coating can form a firmly attached continuous solid film with protective decorative properties. Is a kind of anti-UV ultraviolet coating, polyester resin is the main chain containing ester bond polymer as a monomer, adding alkyd resin, UV absorber can be divided into matte and highlight series according to gloss. It can give colorful aluminum products rich color, and has good gloss and smoothness, as well as superior texture and feel, and can also increase the sense of layer and three-dimensional. It can protect objects from exposure to the atmosphere, ultraviolet radiation, wind, rain, frost and snow. Due to temperature differences, freeze-thaw cycles, corrosive gases and microorganisms, the coating can provide protection. Especially suitable for interior decoration and advertising boards.
Fluorocarbon Coated Aluminum Coil (PVDF)
Fluorocarbon coatings are PVDF resin mainly refers to vinylidene fluoride homopolymer or vinylidene fluoride and other small amounts of fluorinated vinylidene monomer coating. The chemical structure of the fluoric acid base is bound by fluorine/carbonization bonds. The stability and firmness of this chemical structure make the physical properties of fluorocarbon coatings different from those of general coatings. In addition to the wear resistance in terms of mechanical properties, the impact resistance has excellent performance, especially in harsh climates and environments showing long-term fading resistance and UV resistance. After the film is baked at high temperature, the molecular structure of the coating is tight, and it has superior weather resistance. Fluorocarbon coating aluminum coil can meet the high-end building indoor and outdoor aluminum coating, a wide choice of colors, beautiful and solemn appearance, and durability for many magnificent curtain wall buildings around the world add luster. The coating manufacturer's guarantee of the service life of the coating starts from 10 years and 15 years to more than 30-50 years. American research institutions have done comparative tests on fluorocarbon coatings and other coatings, putting different layer samples under the sun in Florida, the United States, and exposing them to the harsh environment of wet and salty air for 12 years, and actually proving that the stability and durability of fluorocarbon coatings are 30 and 80 percent higher than the other two coatings. Fluorocarbon coatings guarantee use in a variety of harsh environments.
3, what are the characteristics of color coated aluminum coil?
Flatness:There is no composite high temperature indentation on the surface. There is no residual stress on the surface and no deformation after shearing.
Decorative:A variety of colors can be selected, can also imitate wood grain, stone grain, there is a realistic physical texture, there is a fresh natural beauty. The pattern can be customized to give customers a wide range of personality choices, which can enrich the humanistic connotation of the product and give people more beautiful enjoyment.
Weather resistance:Good color stability, minimal color difference change. Polyester paint warranty for 10 years, fluorocarbon paint warranty for more than 30 years.
Mechanical:Selection of high-quality aluminum, plastics and adhesives, using advanced composite technology. The product has the flexural and flexural strength required by the decorative plate. Under the four seasons climate, changes in wind pressure, temperature, humidity and other factors will not cause bending, deformation, expansion and so on.
Environmental protection:Resistant to salt-alkali acid rain corrosion, it will not corrode and produce poisonous bacteria, does not release any toxic gases, and does not cause rust of keel and fasteners.
4, What are the applications of color-coated aluminum coil?
color-coated aluminum coil has a rich color range, whether it is residential, large commercial buildings or large exhibition centers, color-coated aluminum coil can be used. Good plasticity and machining properties make it an ideal material for a variety of architectural shapes. Colour-coated aluminium rolls have provided architects, designers and owners with a colour space to personalise facades and ceilings, and are the ideal material for building forms. Whether it is a multi-functional large building or a unique and creative new building, the color-coated aluminum coil can always meet the different requirements of modern and classical architectural styles, and the building is dressed in colorful. Products in the construction, electronic appliances, meters, lighting, packaging, home improvement and many other fields have been applied.
