Neutral degreasing products are preferred for cleaning nonferrous metals without corrosion, dulling and tarnishing. Since they are not strongly acidic or alkaline, they are used only for degreasing without affecting the appearance of soft metals such as aluminum, zinc alloy, brass and copper. The products that do not leave residue and salt on the surface for lines that cannot be rinsed after degreasing are included in this group.
Another area of use is to enhance the degreasing effect in sprayed iron phosphate or zirconium coating lines. Since the pH of this type of baths is in the range of 4 - 6, the pH of the bath is not affected, so degreasing and iron phosphate / zirconium coating can be carried out in the same single bath.
They are preferred because they are used at low concentrations in phosphate coating or zirconium coating baths, do not require high operating temperatures and have effective degreasing performance. The biggest advantage of this type of products is that there is no need for an alkaline degreasing bath in the plant and thus iron phosphate/zirconium coating and degreasing can be carried out in the same bath. In this way, free space is saved in the facility.
Method of Use:
It is used to increase the degreasing effect in spray iron phosphate lines. Since the pH of this type of bath is in the range of 4 - 6, the pH of the bath is not affected, so degreasing and iron phosphate coating can be carried out in the same single bath.
