RUTHUNA® 479 Black Ruthenium Electrolyte
For black decorative coatings - ideal as a perfect final finish
RUTHUNA® 479 Black is the perfect final finish for dark to black surfaces for decorative applications. The black ruthenium electrolyte is strongly acidic and has a long lifetime. It is easy to operate and primarily used for rack plating.
Depending on the degree of blackening, the abrasion resistance of the layers is good to very good. Applying a strike gold layer as an undercoat is strongly recommended. If palladium-nickel or palladium are used as undercoats, strike gold plating will partly not be necessary.
RUTHUNA® 479 Black is suitable for many decorative applications, for instance in the jewellery, bathroom fittings, spectacle frame and writing utensils industries.
