PLATUNA® N1 Platinum Electrolyte for Technical Applications

PLATUNA® N1 Platinum Electrolyte for Technical Applications

Bright and white coatings for electrical contacts

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.
