Functions and Uses：
1. ULTRA Ⅲ is a trivalent chromium blue passivation treatment applicable to passivate the zinc-nickel deposit in both the barrel plating and rack plating. It can generate a glossy and blue protective layer with corrosion resistance on the zinc-nickel alloy deposit composed with 12-15% nickel.
2. The blue passivation coating obtains high temperature resistance and extraordinary thermal resistance.
3. To further enhance the corrosion resistance, the organic sealing agent can be selectively applied in the post-processing. With the application of sealing agent, the original color of passivation coating still can be well-preserved
