Made by Legor Group, this MIDAS® rhodium plating solution (RH5R) is a replenisher for the M-type white rhodium plating electrolyte. This all-inclusive 100ml bottle of solution contains five grams of rhodium with all the additional ingredients necessary to maintain the rhodium electrolyte balance—rhodium, acid and brighteners.

To maintain the stability of the deposition speed, we recommend replenishing your plating solution when the rhodium reaches 80% of its initial concentration. Use the Legor rhodium test kit (available separately) as an inexpensive way to determine if your rhodium bath is still approximately within the desired concentration. Add 20 ml of this replenisher to restore one gram of rhodium to your plating solution.

  • Metal type : Rhodium
  • Size : 3.4 oz. (100ml)
  • Country of origin : Italy

Please Note:

• This solution is not recommended for plating baths under 5 liters.
• Please call Rio Grande tech support for additional information.
