More Information
Summary:The plating bath for the deposition of satin nickel deposits according to the present invention contains at least one quarternary ammonium compound and at least one polyether, the at least one polyether having at least one strongly hydrophobic side chain. As compared to prior art plating baths, this acid plating bath has the advantage that it enables a long period of operation or heating and cooling cycles or filtration cycles, makes it possible to perform the filtration needed for continually operating the bath without using active carbon, requires a lower concentration of nickel than prior art baths to produce the satin gloss finish and has a reduced sensitivity to wetting agents that have been dragged in.
