Black ruthenium from Betzmann Galvanik
Product information “Black ruthenium bath with 5 gram / L Ru
The black ruthenium bath deposits dark to gray-black ruthenium layers. The ruthenium electrolyte works to maintain gloss and a high level of color consistency is achieved. The coatings are non-slip and impress with their decorative color. The maximum achievable coating thickness is 0.2-0.5 µm. For base metals or silverware, pre-gilding or a palladium layer is strongly recommended as an undercoat.
