Black Ruthenium Electrolyte – Ready-to-Use Black Ruthenium Plating Solution (5.0 g/L Ru)
Professional Black Ruthenium Electrolyte for Elegant Dark Grey to Deep Black Ruthenium Coatings
The Black Ruthenium Electrolyte is a premium, ready-to-use black ruthenium plating solution developed for depositing elegant dark grey to deep black ruthenium coatings. The deposited coatings are characterized by excellent color consistency, gloss retention, outstanding wear resistance, and an exclusive decorative appearance.
Specifically designed for decorative electroplating applications, this electrolyte is ideal for finishing jewelry, watches, eyewear frames, luxury accessories, and premium metal components. Its uniform deposition produces sophisticated anthracite to black finishes with excellent durability and long-lasting color stability.
With a ruthenium content of 5.0 g/L Ru, the electrolyte produces decorative ruthenium coatings with a maximum coating thickness of up to 0.5 µm.
Important: When plating silver, copper, brass, bronze, or other base metals, a gold or palladium intermediate layer is strongly recommended to ensure optimum adhesion, color stability, and long-term coating performance.

Processing Recommendations
For optimum plating performance, all workpieces should be thoroughly cleaned, degreased, rinsed, and activated before electroplating.
For silver and other base metals, a gold or palladium intermediate layer is strongly recommended to prevent discoloration and improve adhesion.
Maintaining the recommended operating conditions ensures consistent coating thickness, uniform color, and premium surface quality. Variations in voltage, bath temperature, or plating time may influence the final color shade and deposit characteristics.
