Application and Advantage
 

1. It has excellent dispersing ability and excellent barrel plating effect. The plating layer in LCD area is brighter.

2. Fine grained plating layer, seldom brings hole, and has well corrosion resistance.

3. The bath solution is stable and is easily maintained, and has good tolerance to the impurity.

4. It is used for barrel plating as basal copper, such as steel, copper, copper alloy and zinc alloy.
