Abrasion-resistant and crack-free dark layers
RHODUNA® 471 Black gives jewelry a high-end anthracite to black finish. The level of darkness can be adjusted. The electrolyte is easy to use and the deposits are sure to impress with good color consistency and brightness retention. Thanks to its good corrosion resistance, the electrolyte is ideal for applications where black ruthenium cannot meet abrasion requirements.
The electrolyte produces crack-free surfaces even in thicker layers. On a substrate, it is advisable to pre-coat with either gold or rhodium.
To achieve very dark results and perfect abrasion resistance, it is necessary to post-treat the coated parts with RHODUNA® 471 Black.
