Functions and Uses：
1. ELV-C5000 is a trivalent chromium iridescent passivation treatment applicable to passivate the zinc-nickel deposit in both the barrel plating and rack plating. It can generate a glossy and iridescent protective layer with excellent corrosion resistance on the zinc-nickel alloy deposit composed with 12-15% nickel.
2. ELV-C5000 obtains high temperature resistance and extraordinary thermal resistance. To further enhance the corrosion resistance, the organic sealing agent can be selectively applied to the post-processing. With the application of sealing agent, the original color of passivation coating still can be well-preserved
