High-sulfur nickel additives

Ni-320 high sulfur nickel additive

Ni -320 is an improved high activity nickel flash coating , which coating Shen product of sulfur in the semi-gloss nickel between the nickel duplex nickel all-optical system, it is the most cost-effective to improve corrosion resistance of the coating .

Features:

1. As a layer of impact nickel plating between bright nickel and semi-bright nickel .

2. The sulfur content of the coating can reach 0.1-0.3% , and the potential difference between it and semi-bright nickel is 160-180 millivolts .

3 . Used when high corrosion resistance is needed, it can greatly improve corrosion resistance

4 . The plating solution is stable and has a long service life .
