Gold Echant

It is a high-speed immersion removing solution for removing gold and gold alloy on all base metals. They can be used at room temperature and have little effect on iron, nickel and their alloy materials.

Features

  • It is Gold etchant excluding acid component.
  • Gold only selectively dissolves at room temperature (5 ~ 20 degrees) and at high speed (1 ~ 3㎛ / min).
  • No harmful gas is generated in the treatment process.
  • The pure gold concentration can be peeled up to L/10g.
  • It is very economical to use a new solution when the peeling speed is lowered.
  • A simple water washing process removes the polishing solution remaining on the metal surface.
  • The result of immersing three times for 2 minutes is the same as the result of 6 minutes immersion, which is very easy to use.
