Why do we need to do a fingerprint-free process when coloring stainless steel plates?

The surface color of stainless steel plate is from 2B (no surface processing) at the beginning to now bronze, rose gold, elegant black and so on. From this situation, we can see that the development of 304L stainless steel color plate is getting better and better. However, there is a very strange phenomenon, that is why the fingerprint-free process is done when coloring stainless steel plates?

The fingerprint-free process is to coat a layer of liquid protective layer on the surface of the stainless steel plate, and the color of the protective layer is transparent and colorless or light yellow, and then dry and other operations to improve the anti-fingerprint and anti-pollution properties of the stainless steel plate. , corrosion resistance and wear resistance

The stainless steel color plate with no fingerprint process can avoid leaving fingerprints, dust, sweat, oil, etc. on its surface in terms of aesthetics and durability.

There is no protective layer on the surface of the color stainless steel plate without the fingerprint-free process. During the installation and use process, various corrosive media such as cement, acid water, fingerprints and so on are stained on the surface of the 304L stainless steel color plate, which directly causes it to lose titanium and change the surface color. If it is accidentally scratched, it will greatly shorten the service life of the stainless steel color plate.

However, there are still some flaws. The stainless steel color plate with no fingerprint process should avoid fire source construction, because the anti-fingerprint protective layer applied is easily affected by high temperature.

After weighing the pros and cons, I still choose to add a fingerprint-free process, because the pros outweigh the cons. As long as you choose a professional stainless steel processing manufacturer when purchasing color-free fingerprint-free stainless steel sheets.
