PLATUNA®-Alloy 1 Platinum Ruthenium Electrolyte

PLATUNA®-Alloy 1 Platinum Ruthenium Electrolyte

Extraordinarily abrasion-resistant coatings – saving platinum

PLATUNA®-Alloy 1 is used for depositing smooth, ultra-bright and extraordinarily abrasion-resistant platinum-ruthenium alloy coatings. The acidic electrolyte is used for decorative applications and guarantees light, white layers - crack-free up to 1 μm.

PLATUNA®-Alloy 1 works across a wide operating range and reaches an excellent covering speed. It is used for rack operation.
