Products of color coated aluminum coil becomes more and more ubiquitous in our life, like aluminum doors and windows, aluminum ceilings, aluminum cupboards and aluminum separation boards at home and in public. Sometimes the colors coated onto the products may fade with the passage of time, and some really creative people want to fix things by themselves. They either want to make a faded color brighter or want to change them into a totally different color. Then the problem comes: how to coat aluminum coil with colors?
Technically speaking, there are four ways. Some people also believe that there are only three according to a different classification standard. Here we deal with the complicated one. The first is colored anodizing. If you only want natural color of aluminum coil, then a common anodization process is enough, which helps to form anti-rust layers of the same resistance ability. If you want bright colors, you have to adopt colored anodizing. Theoretically you can coat any color in this way, and the color proves to be bright and lasts very very long time. It’s almost impossible for the colors to fade, but the cost for the process is extremely high! Second, you can coat aluminum coil colors by electrophoresis. Several colors can be coated in this way and the colors can last ten years under normal circumstances. Many aluminum doors have been treated this way. The third proves to be powder coating. Theoretically speaking it can deal with any possible color, but the colors will not be so bright as anodized type. Besides, technique is very important here, because excellent coating will enable a color last for a long time without fading. The fourth method to coat aluminum coil colors is wood transfer printing, which deals with wood designs only.
Based on information above, we can conclude that each coating method entails usage of specialized equipment and relative skills. Therefore, the best choice is to ask professional aluminum coil manufacturers for help if you want to fix color-faded items at home, unless you have both the money and enthusiasm for the tools and skills.
