Umicore supplies electrolytes with pure platinum

Anzeige 12/26/2023 Galvanising | Created by BA

Umicore Metal Deposition Solutions, a unit of the Umicore Group, has developed an electrolyte for electroplating with pure platinum. This enables the deposition of exceptionally thick, homogeneous and crack-free platinum layers.

PLATUNA PT Umicore — PLATUNA PT can be deposited directly onto the carrier material (ideally titanium or nickel) and enables a very thin and homogeneous platinum layer. Platinum is also ideally suited as a surface material in medical sensors, as it is biocompatible, corrosion-resistant and electrically conductive (Image: Umicore)

PLATUNA PT is highly acidic and has a low sulphuric acid content, which makes the electrolyte less aggressive towards the substrate to be coated. It also has a deposition rate of approx. 0.13 μm/min at 5 A/dm², independent of the current intensity.

Compared to other platinum electrolytes, it has a very long shelf life (no precipitation) and is easy to transport and store (no cooling required), enabling large storage quantities and therefore forward-looking cost calculation. PLATUNA PT consists of 99.9 % pure platinum. It provides crack-free layers up to 5 μm with a very uniform layer thickness distribution at a density of 21.4 grams/cubic meter and a hardness of approx. 350 Vickers hardness. It is absolutely haze-free, without color cast, very bright (L* value: 87) and shiny and has a high abrasion resistance as well as very good excellent corrosion and tarnish resistance.
