RHODIUM ELECTROLYTE
RHODUNA® J1 deposits brilliant white, very light and bright surface finishes. This makes the electrolyte ideal for use in decorative applications, such as jewelry, watches or spectacle frames. Special features are its high deposition rate and excellent throwing power. Furthermore, RHODUNA ® J1 deposits layers 0.1 - 0.3 μm thick without cracking. Rhodium is deposited directly onto silver, gold, copper and copper alloys, nickel and nickel alloys. The electrolyte is suitable for rack and barrel plating.
