Qingfeng NK series environment-friendly phosphorus-free conversion nanometer ceramic agent can form nanometer metal oxide film on the metal surface, and has the function of enhancing coating adhesion and corrosion resistance. It can treat steel, galvanized sheet, aluminum alloy and zinc alloy, which is an excellent choice to replace the traditional phosphating process.

Advantages of phosphorus-free conversion agent

Free of nickel, chromium and other heavy metals

Phosphate-free, reducing wastewater treatment

Almost no sediment, reducing waste treatment

Use at normal temperature to save energy

Compatible with old equipment, saving equipment costs

Suitable for steel, aluminum, zinc and other metals

Treatment engineering

Tap water can be used, but the performance of the conversion membrane will be reduced. Recommended tap water conductivity<300 μ s/cm。
