PLATUNA® N1 Platinum Electrolyte
The strongly acidic platinum electrolyte PLATUNA® N1 is used for the deposition of uniform, bright platinum coatings of light color up to 1 μm thickness.
The electrolyte has an extraordinary wide range of current density and allows voltage controlled working. It is also suitable for rack and barrel operation.

PLATUNA® N1 Platinum Electrolyte for Technical Applications
For wearables and cell phones, sales arguments such as a long service life and compatibility with fast charging devices are becoming increasingly crucial. But gold-plated charging contacts and connectors cannot meet these expectations because they corrode through contact with salt water, sweat, etc. RHODUNA® Alloy (rhodium-ruthenium) has therefore been established for years. Due to the current high price, however, we are looking for alternatives.
PLATUNA® N1 is a pure platinum plating solution, which deposits white and bright coatings. The layers itself maintain good electrical properties, high abrasion resistance and excellent corrosion resistance. The hardness of the platinum coating is approx. 500 HV, and the purity reach up to 99.9 wt.%. A platinum layer also offers a huge cost advantage at current precious metal prices.
