Introduction

Semi-bright nickel plating is soft, comparing to the bright nickel plating. It is used for the components required the secondary process such as a bending. Our semi-bright and bright nickel processes can be used for a variety of finishing applications including in duplex or multilayer nickel systems.


Item: HN-M102


Advantages

1. The sulfur content in deposit is less than 0.003%. Potential difference between semi-bright nickel layer and bright nickel layer is 120~145 mV. The corrosion resistance of deposit is excellent.;

2. Good flexibility, excellent leveling and covering power & throwing power.;

3. Strong concentration of additives, low consumption;

4. No coumarin in the bath, less decomposed products;the plating bath is stable and is easy to control;

5. The bath is clear, and won't change color.;

6. It can be used in dual-layer nickel plating or multilayer nickel plating.
