Current price $320.00
Select Size: 1/2 Pint

For professional use only. Superbrite is a ready-to-use rhodium plating solution formulated for professional jewelers and metalsmiths. Each bottle arrives fully pre-mixed — simply pour into your beaker or tank and begin plating immediately. The chemistry delivers a brilliant bright-white, tarnish-resistant finish ideal for fine jewelry production.

Not Returnable. Contains hazardous materials; all sales are final.

Features

  • Ready to use: No mixing required — pour directly into your plating vessel and begin work immediately.
  • Bright-white finish: Produces a premium, consistent bright-white deposit with excellent tarnish resistance.
  • Anti-burn technology: Supports longer plating times across a range of voltages without burning the deposit.
  • Room-temperature operation: Plate at 4 volts at room temperature using a platinized titanium anode — reduces fumes and evaporation compared to heated baths.
  • Broad metal compatibility: Plates directly over gold, platinum, palladium, and nickel. For silver or base metals, apply a nickel or palladium pre-plate first.
  • Production-ready: Delivers reliable, repeatable results suited for professional production environments.

Notes

  • Minimum bath volume: Avoid using less than 500 ml of solution to conserve rhodium — smaller baths reduce current density, limit anode submersion area, and contaminate faster, leading to slower plating and inconsistent deposit quality.
  • Larger baths perform better: The 1 Quart / 2 g size improves plating speed, finish quality, and overall solution longevity.
  • Shipping restrictions: UPS Ground only. No USPS, UPS Next Day Air, 2nd Day Air, or 3-Day Select. Cannot be shipped outside the USA.
  • Successful plating requires proper processes, compatible equipment, and appropriate base metals. Consult manufacturer documentation or professional training resources for guidance.
