Why is it necessary to do fingerprint-free process when plating color stainless steel plate?

[guidebook] : 不锈钢板表面颜色从一开始的2B(无表面加工)到现在古铜、玫瑰金、典雅黑等。从这现状可以看到304L不锈钢彩色板的发展越来越好。然而，有一种很奇怪的现象，那就是为什么镀色不锈钢板时要做无指纹工序?不做无指纹工序的不锈钢彩色板表面没有保护层，在安装使用过程中水泥、酸性水、指纹等各类腐蚀性介质沾到304L不锈钢彩色板表面上，直接导致其掉钛、改变表面颜色，如果不小心刮伤了，那会大大缩短不锈钢彩色板的使用寿命。

Stainless steel plate surface color from the beginning of 2B (no surface processing) to the present antique copper, rose gold, elegant black and so on. From this status quo can see the development of 304L stainless steel color plate is getting better and better. However, there is a very strange phenomenon, that is, why do fingerprint-free process when plating color stainless steel plate?

Fingerprint-free process is to coat the surface of the stainless steel plate with a layer of liquid protective layer, and the color of this layer of protective layer is transparent colorless or yellowish, and then drying and other operations, to improve the stainless steel plate's fingerprint resistance, anti-pollution type, corrosion resistance and wear resistance.

Do the fingerprint-free process of stainless steel color plate both from the aesthetic and durability can be avoided on the surface to leave handprints, dust, sweat, oil stains and so on.

Do not do fingerprint-free process of stainless steel color plate surface without a protective layer, in the process of installation and use of cement, acidic water, fingerprints and other types of corrosive media stained to the surface of the 304L stainless steel color plate, which directly leads to its titanium, change the surface color, if accidentally scratched, it will greatly shorten the service life of stainless steel color plate.

However, there is still a little flaw, do the fingerprint-free process of stainless steel color plate to avoid fire construction, because coated with fingerprint resistant protective layer is susceptible to high temperature.

After weighing the pros and cons, or choose to add fingerprint-free process this step, because the advantages outweigh the disadvantages ah. As long as the purchase of colored fingerprint-free stainless steel sheet choose professional stainless steel processing manufacturers can be.
