1. Wide technique range and good covering ability. The throwing power can increase by 30~60%, the current efficiency is up to 22~24%, non-corrosion at the low current area.
2, High tolerance to impurities.
3. Low content of chromic acid, it is 40% of conventional plating solution. Can reduce the content of chromic acid in waste water, easy to handle.
4. The technique is stable, easy to maintain.
