A. PVD coating film actually has a certain erosion resistance, however, facing with acid and other strong corrosive substances, also difficult to resist. Thus, when using the usual protection to maintain, it is not a better way to choose containing acid and alkali or strong cleaning decontamination, such as toilet cleaner, paint remover, metal cleaning agent, you can wipe gently with a soft cloth in industrial alcohol, if the appearance of a dirt, but also the choice of solvents to dispose of weak acid and base. In addition, if a long time showing in bad situations, or in contact with corrosive liquid, PVD coatings also prone to scattered problems, such as swim pool (fluorine), water (including salt more), high temperature and high wet (steam) and other situations.

B. the use of anti-fingerprint coating. More and more customers choose the good colorful PVD plated stainless steel film product, and then sprayed with a layer of transparency in anti-fingerprint edible vegetable oil, the result is clear, the hand feels no fingerprints, easy to clean, you can also add wear and corrosion function erosion, too. What, then, is a defect injection and non-injection of color inconsistency, coupled with the processing requirements, the cost is not low, the impact of metal texture, as well as aging and other issues. Therefore, before using bound to prudent thinking.

C. subsequent processing problems. PVD coating layer because the substrate has a very good associated with power, not easily falling off, the product can be briefly subsequent machining, such as cutting, folding, bending, cutting. However, welding has large impact on the PVD film, instant film temperature will lead to scattered and discoloration, and thus, the demand for welded stainless steel product to be plated color, it is the best solution to do the member after plating color, can not use plated good PVD membrane materials to manufacturing products.
