Nickel semi-gloss agent

Ni-331. is a new sulfur-free nickel plating process, which can produce a coating with good ductility, moderate brightness and good leveling properties.<br> This process is used as a base layer for multi-layer nickel plating and is suitable for iron and copper parts, zinc die-cast parts and polished copper surfaces. <br> <br> Because of the moderate coating thickness, this combined coating can provide excellent corrosion protection (especially in Step, CASS and Corrodkote tests).<br> <br> There is no need for periodic batch purification.

Product features



The coating is white

and semi-bright luster

The coating has fine crystals, low porosity,and a good columnar structure. It is suitable for various multi-layer Ni-Cr coating systems with high corrosion resistance requirements.





No sulfur, strong

corrosion resistance

The potential difference between the semi-bright nickel layer and the bright nickel layer added with Ni-331 can reach 120-150 mV, which ensures the superior corrosion resistance of the double-layer nickel layer.


Good toughness

The coating is tensile and impact resistant,and has good adhesion with semi-bright nickel and bright nickel coating.





Good leveling

Adopting the new technology

independently developed by Bigely and adding TBC active ingredients, the thin coating can obtain excellent Good leveling effect, which can shorten the plating time and increase the production volume.


Low organic



Ni-331 is made of high-quality raw materials from BASF, Germany, with high purity, less impurities, and the bath is not easy to age, which can reduce the processing frequency.





Low additive


Source manufacturer, high concentration,low dosage.
