RHODUNA® PT PEN Rhodium-Platinum-Electrolyte

PT PEN: Pen variant for targeted, partial rhodium plating

Rhodium creates a brilliant white surface on decorative products. Platinum has enjoyed an incredibly stable price for a number of years, and its name is desirable for all buyer groups. Imagine an alloy that combines the benefits of both precious metals.

With RHODUNA® PT PEN, targeted, partial rhodium plating is possible with a pen plating unit. This is mainly required for multicolor coatings, repair work and coatings of small areas. The layer consists of 40% rhodium and 60% platinum. Notwithstanding that the high-quality alloy can not be distinguished from that of a pure rhodium electrolyte, even with a trained eye. Due to the high societal significance of platinum, your product also gains in psychological value and its price acceptance increases significantly – conversely, for you as a producer a coating with RHODUNA® PT PEN is up to 43% cheaper than with a pure rhodium electrolyte.

Furthermore, RHODUNA® PT PEN not only convinces with cost advantages, but also impresses with high wear resistance and easy handling.
