Process characteristics:

 

1 Both economy and efficiency.

 

2 High efficiency, the process of the cathode current density was significantly higher than the same amount of silver cyanide, silver, can improve work efficiency and equipment utilization.

 

3 Coating with good adhesion to the substrate, good weldability.

 

4 Throwing ability.

 

5 Coating internal stress.

 

6 Bath can be kept stable for more than 2 years.

 

7 Anti-pollution ability, easy maintenance.

 

8 Non-cyanide plating bath formulations, production safety and environmental protection. Fully meet the requirements of environmental protection and production safety.

 

9 Electroplating power supply output voltage less than 1.5 V, the bath composition is stable, not easily broken. Therefore maintenance cycle than cyanide silver plating long, low maintenance costs.
