Umicore Rhoduna® PT ONE - 1gm

SKU: 210-1044




Umicore developed RHODUNA® PT ONE as a unique rhodium alternative that coats jewellery in a white and bright rhodium-platinum alloy with the luster and durability of pure rhodium but at a fraction of the cost. RHODUNA® PT ONE was designed for artisans, so you will need minimal space, equipment, and chemistry to perform the electroplating. Just add water to create the bath. The solution consists of 30% rhodium and 70% platinum with a metal content of one gram per liter to make it more economical while delivering a nearly constant 20/80 rhodium-platinum layer up to 0.3μm thick that is indistinguishable from pure rhodium even to the trained eye.

Because platinum is so highly regarded in its own right, a rhodium-platinum combination delivers equal results while reducing production costs.
