Product knowledge of color coated aluminum strip
Color-coated aluminum strip is a product after deep processing of the surface of aluminum strip, which can greatly improve the weather resistance and corrosion resistance of aluminum strip, and can be painted into various colors, which increases the decorative performance of aluminum. It is one of the technical links of deep processing of aluminum strip.
Color coated aluminum sheet and strip product introduction
1. Aluminum strip refers to a rolled product with aluminum as the main raw material and mixed with other alloy elements, which has a rectangular cross-section, uniform thickness and greater than 0.20mm.
2. Sheets are delivered in straight shapes, and strips are delivered in rolls.
3. Color-coated aluminum sheet (coil) is to use special paint to color the surface of aluminum sheet and strip. Because the performance of aluminum alloy is very stable, it is not easy to be corroded. After special treatment (fluorocarbon paint) on the surface, it can guarantee that it will not fade for at least 30 years, and There are different functions due to different coatings.
Classification of color coated aluminum strip
Color-coated aluminum strips are generally divided into two categories according to the different coatings, polyester coating (PE) and fluorocarbon coating (PVDF).
|Weather resistance (mainly UV)
|2-5 years, there will be obvious color difference on the sunny side
|10-20 years without color difference
|better;But the new product high-gloss fluorocarbon coating
Appears to compensate for the brightness of fluorocarbon coatings
|There is a huge difference, the general PE is only 1/10 of the price of PVDF
Performance characteristics of color coated PVDF
Fluorocarbon coatings are a general term for a series of coatings with fluorine-containing resin as the main film-forming substance. It is modified on the basis of fluorine resin.
Color coated aluminum strip is a new type of coating material that is processed and processed. Its main feature is that the resin contains a large number of F-C bonds, and its bond energy is485KJ/mol ranks first among all chemical bonds. Under the action of heat and light (including ultraviolet rays), F-C is difficult to break,
Therefore, Color coated aluminum strip shows super long weather resistance and chemical medium corrosion resistance, so its stability is the best among all resin coatings.
This determines that it has better performance than other types of coating materials, so it is called “the king of coatings”.
In the field of aluminum sheet and strip coating, fluorocarbon (PVDF) coating is the absolute highest level of coating material.
Application field of color coated aluminum strip
Color-coated aluminum sheets are mainly used in building decoration materials, home appliance panels, food packaging (pop cans), transportation and other fields.
Building decoration materials: roof panels, ceiling panels, honeycomb panels, insulation panels, rolling doors, shutters, aluminum curtain wall panels
Materials for home appliances: range hoods, refrigerators, air conditioners, panels for the inner compartment of refrigerators, etc.
Food packaging: can top cover, can pull ring, aerosol spray cap
Transportation: box truck shell, box truck inner wall, vehicle interior.
Color coated aluminum strip specification
Color coated aluminum strips are commonly used in construction, electronics, automobiles, etc. Different application scenarios will have different specifications for color-coated aluminum strips.
Alloy: color coated aluminum strips are usually made of various aluminum alloys, and the commonly used ones are 1000, 3000 and 5000 series.
Thickness: 0.1mm to 3mm.
Coating Type: Common coatings include polyester, polyurethane (PU), polyvinylidene fluoride (PVDF), or epoxy.
Color: customized according to customer needs.

Color coated aluminum strip density
Color-coated aluminum strips are cut from 1000-8000 series aluminum alloy rolls, with a density of 2.68-2.72g/cm³ and a lighter weight.
