Description
Superbrite rhodium plating solution arrives pre-mixed so you can pour it straight into a beaker or tank and start plating at the bench. Cohler formulates it for professional jewelers and metalsmiths, and the chemistry lays down a brilliant bright white, tarnish-resistant finish suited to fine jewelry production. For professional use only.
Not returnable. Contains hazardous materials, and all sales are final.
Features
- Ready to use: No mixing required, so you 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, which reduces fumes and evaporation compared to heated baths.
- Production ready: Delivers reliable, repeatable results suited to professional production environments.
Available Options
| Part # | Size | Rhodium Content |
|---|---|---|
| 145.546 | ½ Pint | 0.5 g Rhodium |
| 145.547 | 1 Pint | 1 g Rhodium |
| 145.548 | 1 Quart | 2 g Rhodium |
Compatibility
- Plates directly over gold, platinum, palladium, and nickel.
- For silver or base metals, apply a nickel or palladium pre-plate first.
- Use a platinized titanium anode at 4 volts and room temperature.
Notes
- Minimum bath volume: Avoid using less than 500 ml of solution to conserve rhodium, since 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.
