Pen Plater Superblack Black Rhodium Solution

Cohler Superblack Pen Black Rhodium Solution produces a deeper, darker grey-black rhodium plate on gold and other precious metals than standard black pen rhodium. Formulated specifically for pen plating, it uses a different pH and higher concentration than bath rhodium solutions to deliver crisp two-tone accents, touch-up repairs, and uniform dark finishes. For professional use only.

Features

• Deeper dark finish: Rich grey-black tone for bold contrast and modern looks.
• Pen-plating optimized: Concentrated chemistry for fine control and localized application.
• Durable and tarnish-resistant: Suitable for high-wear accents and touch-ups.
• Great for two-tone work: Selective plating on rings, bezels, and textured elements.
• Versatile applications: Dark accents to complement black or deep-hued stones, selective two-tone effects, and restoration touch-ups on gold and other precious-metal substrates.
