Bath & Brush Application

Gold Plating Services’ Bright Palladium Solution is a pure palladium plating solution for decorative use, commonly know as white gold. It produces a premium, white, mirror-bright finish that plates quickly and can substitute for rhodium. The deposited finish is tarnish resistant, very durable, and nickel free. This solution produces a deposit that can serve as a diffusion barrier under gold plating in most cases. 

Usage Notes: The surface to be plated must be clean and free of any corrosion or oxidation and should "wet out" prior to activation. Activation of the surface should be appropriate for the base material. The activation surface should not be touched and should be rinsed and electroplated prior to drying to prevent re-oxidation.

Mohs Hardness -   4.75     
Content -   2.5 grams palladium/liter 
Theoretical Coverage -   1 gram of palladium has a coverage of ~508 in² when plated to an average decorative thickness, and a coverage of ~127 in² when plated to one micron

Note: This coverage is based on the assumption that all palladium in the solution will be deposited. In actual practice this is not likely since there is normally solution loss during use.

Operating Conditions

Temperature -   120° F (too high of temperature can cause burning)

Anode -   Bath: Bagged Graphite or Platinized Titanium 
Brush: Platinized Titanium Bit with a Cotton Sleeve

Voltage -   Bath: 1.5 - 2 Volts (optimum 2 Volts)
Brush: 3.5 Volts 

Time -   15 - 30 seconds for a normal decorative plate; plating generally does not exceed 2 minutes for a heavy plate due to metallic hardness

pH -   5.5 - 6 (optimum 5.8)

Agitation -   Relative movement between work and solution is recommended 

Filtration -   Optional 

Shelf Life -   If stored at room temperature, properly sealed solution has a shelf life of ~2 years
