Acid based plating solution plates a very dark gray (anthracite) color, almost black. Can be used alone or as a contrast color on both yellow and white metals. For bath plating only, cannot be used for pen plating. 4 oz. bottle has 100 ml of solution containing 2 grams of Ruthenium.
To make up 1 liter of electrolyte, stir 100 ml of Ruthuna® 475 Black slowly into 800 ml of deionized water and fill up to 1 liter with deionized water.
Umicore Black Ruthenium 475 is strongly recommended to be plated over an undercoat of 18K for proper adhesion. When plating over non-precious metals, plate the item with gold prior to using Black Ruthenium.
Please take note:
- Due to the fluctuating prices of precious metals, Rhodium prices change daily.
