RHODUNA® 271 Rhodium Electrolyte

RHODUNA® 271 Rhodium Electrolyte

Pen rhodium plating for abrasion resistant and bright coatings

With RHODUNA® 271, targeted, partial rhodium plating is possible with a pen plating unit. In this process, small surface elements of the article are rhodium-plated by means of direct current and by wiping contact with the tip of the pad. The process is mainly used to apply decorative patterns to jewelry, eyeglasses, etc.

Although decorative applications typically require layer thicknesses of 0.1 - 0.2 μm, the process also provides bright, pure white layers up to approx. 1 μm. RHODUNA® 271 is characterized by a particularly fast deposition rate and high deposition efficiency.
