NF-501 Dehydration Anti-Discoloration Agent
NF-501 dehydration anti-tarnish agent is an advanced post-treatment solution for plated components. When immersed in NF-501 solution and subsequently rinsed, plated parts develop a transparent hydrophobic protective film that prevents water marks and drying traces while significantly enhancing rust and tarnish resistance.
Key Properties
- Low Concentration: NF-501 operates effectively at just 0.3-1% concentration, delivering long-lasting performance with minimal usage.
- Rapid Dehydration: Achieves complete dehydration in just 5-10 seconds of immersion, ensuring efficient processing.
- Superior Protection: Contains multiple synergistic inhibitors that significantly improve rust and discoloration resistance.
- Easy Maintenance: Wide concentration range (0.3-1%) provides excellent dehydration capacity with simple maintenance requirements.
Applications
Suitable for zinc plating, barrel nickel plating, and chrome plating post-treatment processes. Can effectively replace chromate treatment after barrel nickel plating, providing dual benefits of dehydration and anti-tarnish protection.

Solution Preparation
Prepare the dehydration solution using deionized water. Add the measured quantity of NF-501 dehydrating agent and stir thoroughly until evenly mixed. The solution is then ready for use.
Maintenance
When dehydration capacity decreases, replenish the solution with additional NF-501 agent as needed to maintain optimal performance.
