Superbrite Pen Rhodium Solutions

Pen plating puts rhodium exactly where you want it at the bench, on a prong, a bezel or a logo, without dipping the whole piece. Superbrite Pen Rhodium from Cohler is a highly concentrated, sulfuric acid-based pen plating chemistry formulated for precise, localized rhodium deposits. Compared to bath rhodium, pen solutions use a different pH and higher metal concentration to deliver rapid coverage, excellent throwing power, and a brilliant mirror-white finish, ideal for two-tone accents, small touch-ups, and quick repair work. For professional use only.

Features

• Brilliant mirror-white finish: Fast depositing with strong throwing power for professional-quality results.
• Anti-burn technology: Plates at various voltages for longer without burning; recommended operating voltage is approximately 6 V at room temperature.
• Precision placement: Optimized for pen-plating wands and tips for exact, localized application.
• Two-tone and repair work: Ideal for localizing rhodium to prongs, bezels, logos, and high-wear points.
• High concentration formula: Different pH than bath rhodium solutions, formulated specifically for pen plating use.

Available Options

Compatibility

Plate directly over gold, platinum, palladium, or nickel. When plating over silver or base metals, apply a nickel or palladium pre-plate for best adhesion and color consistency. Not all metals can be rhodium plated.

Notes

• Surface preparation: Thorough cleaning and activation or strike steps, as required, are essential for adhesion and uniform color.
• Equipment: Requires pen-plating equipment with compatible tips. Successful plating depends on correct equipment and multi-step processes.
• Safety: Sulfuric acid-based, so wear appropriate PPE and ensure adequate ventilation during use.
• Hazardous material: Ships via UPS Ground only within the USA. No USPS or air services. Not returnable; all sales final.
