PALLUNA® 459 Palladium Electrolyte
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.

PALLUNA® ACF-100 Palladium-Nickel Electrolyte
The new palladium nickel electrolyte PALLUNA® ACF-100 has all the technical advantages of other electrolytes – but without the smell of ammonia. The deposited layers are ductile, crack-free and resistant to abrasion. Furthermore, PALLUNA® ACF-100 has the cost benefit on its side: With comparable contact properties to those of hard gold, the palladium-nickel layer is by far the less expensive alternative.
PALLUNA® ACF-100 is a high-speed electrolyte, free of ammonia and chloride, for depositing a bright palladium-nickel-alloy in reel-to-reel lines (selective dipping, jet plating, brush plating) and in tabplaters.
Depending on the operation conditions, the electrolyte deposits alloy coatings with approx. 80 % of Pd. The alloy composition is largely independent of the current density. Electrolyte maintenance without ammonia and chloride. Breakdown products could be removed by carbon treatment easily. Continuous carbon treatment is feasible.
A brightener specially developed for PALLUNA® ACF-100 enables analytical electrolyte control. Thus, the increased requirements for new quality standards and stricter guidelines such as IATF 16949 can also be mapped by a compliant process control.

PALLUNA® ACF-200 Palladium-Nickel Electrolyte
PALLUNA® ACF-200 is operated without ammonia, thus avoiding offensive smells caused by pungent ammonia gases. Since no chloride is used in the electrolyte, the lifetime of the anodes is considerably longer and equipment corrosion is strongly reduced. By means of continuous active carbon purification, interfering organic decomposition products can be effectively removed from the electrolyte.
Depending on the operating conditions, the electrolyte deposits alloy coatings containing approx. 80 % of palladium. The palladium-nickel layers are hard, resistant to wear and corrosion, they are characterized by good ductility and low internal stress. In combination with flash gold, bondabilities comparable to those of soft gold surfaces can be reached.
PALLUNA® ACF-200 has the cost advantage on its side: With contact properties similar to those of hard gold, palladiumnickel is the clearly less expensive alternative.
