High-sulfur nickel plating additives

Ni-320 is an improved highly active nickel coating. The coating is deposited between the sulfur-free semi-gloss nickel and full-gloss nickel double-layer nickel system. It is the most economical and effective way to improve the corrosion resistance of the coating.

Product features



Can greatly improve

the corrosion

resistance of

multi-layer nickel

After adding Ni-320, the sulfur content of the coating can reach 0.1-0.2%,and the potential difference with semi-gloss nickel is 160-180 millivolts, and the protective performance is significantly improved.





Can reduce the total

thickness of the

coating by more than 30%


Under the same corrosion performance requirements, the three-layer nickel coating with Ni-320 added compared to the double-layer nickel coating can reduce the total thickness of the coating and reduce the cost by about 5-10%.


Good toughness

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





Uniform sulfur content

in high and low current

areas of the coating

Adopting the new technology

independently developed by Bigely and adding TBC active ingredients, the coating has fine crystallization and uniform sulfur content in the high and low current regions, which is suitable for the

multi-layer nickel electroplating process of various multi-angle deep concave complicated.


Low additive


Source manufacturer, high concentration,low dosage.





Stable plating solution

and long service life

Made with excellent raw materials from German BASF, with high purity and less impurities.
