PALLUNA® 459 Palladium Electrolyte

PALLUNA® 459 Palladium Electrolyte

The intermediate layer as the perfect diffusion barrier for jewelry

PALLUNA® 459 deposits brillant, bright and extremely low-pore pure palladium layers. It can be used as pre-palladium, as a diffusion barrier before rhodium plating or gold plating or as a final layer for decorative applications.

The palladium electrolyte is very easy to use. Due to the excellent throwing power, expensive precious metal can be saved, making this electrolyte economically attractive.
