Description Instructions

RHODUNA® PT ONE is the latest addition to the Umicore family of plating products. RHODUNA® PT ONE is an economical alternative for pure rhodium without compromising quality and durability.

Made to the highest standards in plating solutions, it was designed for small scale baths and the metal content is reduced to one gram per liter. This allows extremely economical rhodium plating starting with the first liter of electrolyte - and with almost constant layer properties. Additional benefits include easy handling thanks to a simple work area and the reduction of the necessary components to an absolute minimum - apart from the initial concentrate, only water is required for its electrolyte makeup.

Once plated with RHODUNA® PT ONE, layers consist of 20% rhodium and 80% platinum. Nevertheless, the high-quality alloy cannot be distinguished from that of a pure rhodium electrolyte, but saves the jeweller on plating costs when Rhodium is at all-time highs.

Due to the high social value of platinum, your product simultaneously gains psychological value and its price acceptance increases significantly - conversely, for you as a producer, a coating with RHODUNA® PT ONE is far more attractive in terms of price than one with a pure rhodium electrolyte. Made in Germany.
