Color Gold Bath, Prod-ID: NC200


NC200 is an alkaline-low cyanide electrolyte for the deposition of bright yellow gold coatings. The gold has a fineness of 24 carats. The achievable layer thickness is Max. 0.1-0.2 micron. By adding special color solutions, the color of the gold deposition can be changed in a controlled manner. There are essentially 3 color solutions available for this purpose:

  1. Color solution green
  2. Color Solution red
  3. Color solution yellow

The gold electrolyte contains low amount of free cyanide and can therefore be deposited with a constant color over a long period of time. The long-term stable NC200 electrolyte is easy to operate and suitable for rack and barrel. It is used for decorative applications.

Gold content: 1 g Au/1000 ml
