Color-coated aluminum coils are surface-coated aluminum coils or aluminum coils. Common coated aluminum coils include fluorocarbon color-coated aluminum coils and polyester color-coated aluminum coils, which are widely used in veneers, aluminum honeycomb panels, aluminum ceilings, roof surfaces, scraps, cans, electronic products, etc. Color-coated aluminum coils have stable performance and are not easy to corrode. Moreover, the surface of color-coated aluminum coils has been specially treated to achieve a 50-year quality assurance. The weight per unit volume is the lightest among metal materials and is currently the most popular new material.
Types of color-coated aluminum coils
Color-coated aluminum coils are divided into polyester coated aluminum coils (PE) and fluorocarbon coated aluminum coils (PVDF) according to the coating. The polyester coating formed on the surface of the aluminum plate after multiple baking can form a firmly attached continuous solid film with protective decorative properties. It is an anti-ultraviolet coating. Polyester resin is a high-molecular polymer containing ester bonds in the main chain and alkyd resin added. UV absorbers can be divided into matte and high-gloss series according to glossiness. It can give aluminum products rich colors, good gloss and smoothness, as well as superior texture and feel. In addition, it can increase the layering and three-dimensional sense of aluminum products. It can protect objects exposed to the atmosphere, attacked by ultraviolet rays, wind, rain, frost, and snow from temperature differences, freeze-thaw cycles, corrosive gases, microorganisms, etc., and the coating can play a protective role. Color-coated aluminum coils are particularly suitable for interior decoration and billboards.
The fluorocarbon coating of fluorocarbon polyester color-coated aluminum coils is PVDF resin, mainly referring to vinylidene fluoride homopolymer or copolymer of vinylidene fluoride and other small amounts of fluorine-containing vinyl monomers. Fluorocarbon coatings can be divided into traditional fluorocarbon coatings and nano-fluorocarbon coatings according to the surface film structure. Fluorocarbon polyester color-coated aluminum coils are particularly suitable for indoor and outdoor decoration and display in public places, commercial chains, exhibition advertisements, etc.
Characteristics of color-coated aluminum coils
These coated aluminum coils have the characteristics of flatness.
There is no composite high-temperature indentation on the surface, no residual tension on the board surface, and no deformation after shearing.
These coated aluminum coils have a decorative effect.
Color-coated aluminum coils are painted with wood grain, stone grain and other coatings, with realistic solid texture and vivid natural beauty. The patterns can be made arbitrarily, bringing customers a wide range of personalized choices, enriching the humanistic connotation of the product, and giving people more aesthetic enjoyment.
These painted aluminum coils are weather-resistant
The paint patterns formed by continuous coating and high-temperature baking have high gloss retention, good color stability, and small color difference changes. The shelf life of polyester paint for color-coated aluminum coils is 10 years, and the shelf life of fluorocarbon paint for color-coated aluminum coils is 20 years.
Color-coated aluminum coils are mechanical.
Selecting high-quality aluminum, plastic, adhesives, and using advanced composite technology, color-coated aluminum coils have the bending and folding strength required by decorative panels. In the four seasons, they will not bend, deform, expand, etc. due to changes in wind pressure, temperature, humidity and other factors.
Color-coated aluminum coils are environmentally friendly.
Resistant to salt, alkali, acid and rain corrosion, color-coated aluminum coils will not corrode and produce toxic bacteria, will not release any toxic gases, will not rust the keel and fasteners, and are flame retardant.
Application of Color-coated Aluminum Coils
Color-coated aluminum coils are rich in colors. Whether it is residential buildings, large commercial outlets, or large exhibition centers, color-coated aluminum coils can add color to them. The good plasticity and processability of color-coated aluminum coils make it an ideal material for various architectural shapes. Color-coated aluminum coils provide architects, designers, and owners with customized color spaces for exterior walls and ceilings, and are the best materials for architectural shapes. Whether it is a multifunctional large-scale building or a unique and creative new building, color-coated aluminum coils can always meet the different requirements of modern and classical architectural styles, making the building more colorful. Color-coated aluminum coils are used in many fields such as electronic appliances, instruments and meters, lighting, packaging, and home decoration.
