PALLUNA® 458 Pure Palladium Electrolyte

Neutral pure palladium electrolyte less sensitive to cyanide

PALLUNA® 458 is a neutral pure palladium electrolyte (pH-value 7.0) without free ammonia. It deposits bright, light white coatings low in pores.

Compared to previous palladium electrolytes, the process is characterized by a considerably higher tolerance to contamination with cyanide. Due to its excellent throwing power, expensive precious metal can be saved.

PALLUNA® 458 is suitable for decorative and technical applications, for rack and barrel operation.
