Information
Characteristic:

Fast bright dipping, good dispersibility in low current density area;
Aesthetic and pure white coating;
Stable plating solution and few resolvents;
Suitable for electroplating process requiring fast bright dipping.

Application:

Applicable to barrel nickel plating of jewelries, ornaments of boxes and bags and such hardwares as lighters.

Advantage introduction:

Ni6A: Commonly known as brightener. It is responsible for bright dipping and leveling. When the content in the plating solution is insufficient, the bright dipping is slow; when the content is too high, the area with low current density will become dark and the coating becomes brittle;
Ni6B: Commonly known as auxiliary brightener, also known as softener. It eliminates the brittleness caused by the brightener and promotes uniform distribution of the coating. When the content in the plating solution is insufficient, the area with low current density will become dark and the coating becomes brittle. When the content is too high, the bright dipping may become slow;
Niw1: Wetting agent. It can decrease the surface tension of plating solution and avoid presence of pinholes and pockmarks.
