Black Rhodium - black rhodium plating by Betzmann Galvanik
The ready-to-use black rhodium electrolyte is suitable for both pin, pad and bath electroplating!
It deposits dark anthracite-gray, extremely decorative rhodium layers. The layers are very abrasion resistant, color consistent and uniform.
The Black Rhodium Electrolyte from Betzmann Galvanik is preferred for decorative coatings in the jewelry and eyewear industries. This black rhodium electrolyte is characterized by simple bath management and very user-friendly handling. It also operates at room temperature, which means that time- and energy-consuming heating can be omitted. Layers down to 0.5 µm can be deposited.
