Legor RHODIENS Platinum-Rhodium Plating Solution 1g/250ml - Bright White Finish Alternative to Rhodium (RH2XL Alternative)

The Legor RHODIENS Platinum-Rhodium Plating Solution is engineered as a cost-effective alternative to traditional pure rhodium plating, delivering a bright white, reflective finish while reducing reliance on volatile rhodium pricing.

This advanced electrolytic system produces a shiny platinum-rhodium alloy deposit, combining the aesthetic qualities of rhodium with improved durability and process stability. Ideal for both decorative and protective applications, RHODIENS offers excellent coverage and adhesion across a wide range of jewellery pieces.

Its formulation is designed for consistent performance in smaller plating setups, allowing users to maintain high-quality results while improving cost control and efficiency.

Pre-Treatment Recommendations:

Apply directly on gold, silver, palladium and palladium alloys. For base metals such as copper or brass, an intermediate precious metal layer is required to prevent contamination and ensure proper adhesion.

Post-Treatment Recommendations:

After plating, rinse in demineralised water and dry thoroughly. A final hot rinse can enhance brightness and overall finish quality.

Water Quality:

Use demineralised water with conductivity below 3 µS/cm to prevent contamination and maintain plating performance.

Maintenance Guidelines:

Designed for small-scale systems (up to 5L), this solution is intended to be used until exhaustion without replenishment, simplifying operation and reducing maintenance requirements.
