PURE PALLADIUM ELECTROLYTE
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.
Advantages
• Light white, pure palladium coatings

• Ductile layers for decorative and technical applications
• Bright, low-pore coatings
• Crack-free layers > 3 μm possible
• Suitable for rack and barrel
Applications
• Jewellery
• Watches
• Semiconductors
• Printed circuit boards
