202 Direct nickel plating process on iron
★Use and characteristics
1.It is especially suitable for direct iron plating process, It has a fast speed of bright dipping, excellent leveling.
2 The coating is soft and corrosion resistance, and it is suitable for the 717 chrome substitute plating and plating after nickel plating.
3 the concentration of the bright agent is high, the consumption is little, and the impurity tolerance is high.
4 The plating solution is stable, easy to operate.
