Application and Advantage
1. Non-cyanide.
2. Suitable for rack plating and barrel plating.
3. Obtain bright and esthetic deposit in a wide range of current density.
4. Even thickness of deposit, excellent dispersive ability.
5. The deposit is very soft, easy to do chromate passivation. It can be treated to other shapes after plating.
6. The process is stable, high tolerance against impurities, good temperature resistance.
