Blue passivator for electroplating zinc-nickel alloy

Zn-323 can produce a blue passivation layer with excellent corrosion resistance on zinc-nickel alloy coatings with a nickel content of 12-15%. Through a simple dipping process, a uniform blue passivation layer can be produced with good bonding force. The sealing treatment can further improve the corrosion resistance and make the appearance of the coating change into the color of silver-stainless steel.

hexavalent chromium

Green products, through SGS product

testing and certification, meet ROHS, ELV regulatory requirements, use at ease



blue passivation



A bright and uniform

blue passivation film

can be obtained

Passivation film is not easy

to turn yellow and does not fade


Good corrosion resistance

TBC active ingredients are added to the

product, which has strong anti-rust

performance. When the thickness of

the coating layer is ≥ 5-8 microns, the

resistance to NSS>350 hours can meet

the functional requirements of auto parts

  Reduce defective products and save costs


High temperature Resistance

High temperature


The passivation film is baked at a

temperature of 200°C, the appearance

is rarely changed, and its NSS resistance

can still exceed 350 hours)


Wide application

PH range
