Trivalent Coating Project
- Objective: Improve salt spray testing performance from 12 hours to 120 hours on clear zinc chain products.
- Background: Process: Clean chain, zinc plate chain and apply trivalent coating.
- Chain meets ASTM B633 Fe/Zn 5 Type III requirements.
- Implemented a new trivalent coating along with process and equipment improvements.
- The new trivalent coating is microscopically thinner with an improved resistance to a salt spray testing environment.
- No change to the overall process flow.
Conclusion:
- Salt spray testing per ASTM B117 improved to 120+ hours to white rust.
- The new coating has a consistent attractive bright finish.
