Platinum Electrolytes

PLATUNA® N1 acid platinum electrolyte deposits smooth, brilliant platinum coatings up to 1 μm, with an approximate hardness of 500 HV. Bath has a wide operating window; rack and barrel systems are compatible.

PLATUNA-ALLOY 1 platinum-ruthenium alloy electrolyte deposits smooth, brilliant and extremely abrasion-resistant coatings. The acidic electrolyte is used for decorative applications and guarantees light, white layers while conserving costly platinum. Deposits are crack-free up to 1 μm.

Platuna-Alloy 1 has a high deposition rate, and is used with conventional rack systems. It is compatible across a wide operating range.

PLATUNA PT pure platinum electrolyte deposits smooth, crack-free platinum coatings up to a layer thickness of 5 μm. The deposited layers have a brilliant luster and, in contrast to conventional platinum coatings, do not exhibit a yellow tint.

The electrolyte has a low sulfuric acid content, so it is less aggressive to the substrate. Deposition rate is independent of current density, so distribution uniformity is easily achieved. No precipitation occurs and the platinum concentrate can be stored at ambient temperature.

PLATUNA ALLOY RH platinum-rhodium electrolyte deposits abrasion-resistant platinum-rhodium layers. Sparkling, high-luster crack-free coatings can be deposited up to a layer thickness of 0.5 μm. The deposited coatings have no yellow tint.

Rhodium content contributes high hardness to the coating; the electrolyte’s low sulfuric acid content is also less aggressive to the substrate. Deposition rate is independent of current density, a characteristic that optimizes layer thickness distribution. No precipitation occurs and the platinum concentrate can be stored at ambient temperature.
