Rhodium Electrolyte BMG‑085.1 – White Rhodium
Bright, Hard and Corrosion‑Resistant Rhodium Plating Solution
Short Description
The Rhodium Electrolyte BMG‑085.1 is a ready‑to‑use electroplating solution for rhodium, designed to produce exceptionally bright, white, hard and durable rhodium deposits. It is formulated for long shelf life and can be used in both tank plating, brush plating and tampon/pen plating. This makes it ideal for decorative and functional coatings, particularly where permanent brilliance and corrosion resistance are required.
The plated layer remains bright and does not tarnish like silver, making it a popular choice in jewelry, watches, accessories, and high‑wear surfaces.
What is this Rhodium Electrolyte used for?
Rhodium electroplating provides a thin yet extremely durable white metal coating that offers:
-
Bright, brilliant white finish
-
High abrasion and wear resistance
-
Outstanding corrosion resistance
-
Surface protection for precious metals and alloys
-
Enhanced durability and appearance on jewelry, watches, eyeglass frames, and decorative items
It is frequently used as a top layer over gold, palladium or other base finishes for both decorative appeal and functional enhancement.
How does rhodium plating work? (simple explanation)
Rhodium plating uses electrolytic deposition to transfer rhodium onto a prepared metal surface:
-
The workpiece must be extremely clean, polished and degreased before plating.
-
The cleaned part is connected as the cathode (negative pole).
-
A platinum or platinum‑coated titanium anode is used as the positive pole.
-
When DC current is applied, rhodium ions in the electrolyte are reduced and deposit as a bright, uniform rhodium layer.
Because rhodium is one of the hardest precious metals, even very thin layers provide excellent scratch, wear and tarnish resistance.
Advantages of Rhodium Electrolyte BMG‑085.1
-
Produces a very bright white finish, brighter than silver
-
High hardness and wear resistance, excellent for high‑use surfaces
-
Excellent corrosion resistance and tarnish protection
-
Suitable for tank, brush and pen plating
-
Can be used on gold, palladium, silver and other base layers

Thoroughly polish, clean and degrease surfaces before plating.
-
Rinse with clean water and, if necessary, use a suitable acid dip or activator before rhodium plating.
Tank Plating:
-
Maintain plating voltage and current per recommended parameters.
-
Use proper agitation for best uniform coverage on complex shapes.
Brush / Pen Plating:
-
Keep the plating stylus moving evenly across the workpiece.
-
Ensure a good contact clamp connection for a consistent layer.
Tips:
-
Thin rhodium layers (< 1 µm) are typical and provide excellent finish and protection.
-
Mask areas not to be plated using appropriate masking methods.
Safety Information
Rhodium plating solutions are strongly acidic and corrosive and must be handled with care:
-
Wear chemical‑resistant gloves, eye protection and protective clothing.
-
Avoid contact with skin and eyes; rinse thoroughly with water if contact occurs.
-
Use only in well‑ventilated areas to avoid inhalation of fumes.
-
Do not ingest; keep out of reach of children.
-
Dispose of waste and rinse water according to local environmental regulations due to heavy metal content.

Anode pad / tampon / anode sleeve / fuzzy sleeve / replacement fabric pad puffy from Betzmann Galvanik. This puffy fabric pad / anode sleeve or also called tampon is absolutely recommended for all plating processes. Optimally suitable for all coatings and electrolytes. The coating of larger areas is also quite fast with this pad. The insertion hole is larger than the electrode and therefore it happens that the moist anode pad slips off. Therefore, fix the pad on the electrode with a small rubber band.
White Palladium Electrolyte 10 g/L BMG‑101M High‑Performance Palladium Plating Solution for Bright, Silver‑White Coatings Short Description The White Palladium Electrolyte 10 g/L BMG‑101M is a premium electroplating solution designed to deposit bright, silver‑white palladium layers. With a palladium concentration of approximately 10 g per liter, this electrolyte produces a brilliant, metallic finish that is even more striking than traditional nickel plating. real-gold.de It can be used both as a hard decorative top layer and as a nickel‑free barrier layer in multi‑step plating systems. real-gold.de Applications White palladium plating is suitable for: Applying bright silver‑white palladium coatings Nickel‑free barrier layers between copper/brass and gold Decorative finishes with high corrosion resistance Prepping surfaces for subsequent gold plating Alternatives to silver plating, as palladium does not tarnish easily This makes it especially useful for jewelry, electronics, and other applications where an elegant, durable, and nickel‑free surface is desired. How White Palladium Plating Works (Simple Explanation) Palladium electroplating works by using direct current (DC) to reduce palladium ions from the electrolyte onto the surface of the workpiece: Surface Preparation: Clean and degrease the part thoroughly.
