Dark ruthenium coatings without strike gold plating
RUTHUNA® 490 Black is a neutral electrolyte for brightness retaining, dark grey to anthracite coatings. The black ruthenium electrolyte is easy to operate and has a good colour constancy.
RUTHUNA® 490 Black permits the direct plating of copper, nickel, brass or bronze. This means that strike gold plating or strike plating with palladium or palladium alloys is not necessary, which leads to enormous precious metal cost savings.
The black ruthenium electrolyte is suitable for decorative applications, above all in the clothing industry. It can be used for rack and barrel plating operations. Due to its high abrasion resistance, subsequent lacquering is not necessary, reducing the number of further process steps. Its positive features make themselves apparent even at a low ruthenium concentration of just 2 g/l.
