Rhodium Weiß + Schwarz

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 Long‑lasting bath with extended shelf life (over 5 years) Technical Parameters The following values represent typical operating conditions for a rhodium plating solution with ~2 g Rhodium content per liter:  PropertyTypical Value / RangeElectrolyte typeRhodium plating solutionRhodium contentapprox. 2 g/LpH value< 1 (strongly acidic)Operating temperature20–35 °C (can also work up to ~40 °C)Voltageapprox. 2–3 VCurrent densityapprox. 0.5–2 A/dm²Anode materialPlatinum‑coated titaniumTypical exposure time2–10 minutesDeposit appearanceBright, brilliant whiteDeposit hardnesshigh (≈ 800–900 HV)Maximum thicknessup to ~1 µm (thin decorative layer)Deposit densityapprox. 12.4 g/cm³ These parameters reflect typical conditions for rhodium plating baths producing high‑quality decorative coatings.  Application Instructions (Detailed) Surface Preparation: 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.  Conclusion The Rhodium Electrolyte BMG‑085.1 produces brilliant white, hard and corrosion‑resistant rhodium coatings, perfect for decorative and functional requirements in jewelry, watches and precision components. With careful surface preparation and adherence to operating parameters, this solution delivers consistent, high‑quality rhodium layers suitable for both hobbyists and professional applications.

Blackening Additive for Black Rhodium / Ruthenium BMG-090.2M Additive for intensifying dark ruthenium and black rhodium electroplated finishes Short Description The Blackening Additive BMG-090.2M is a specialized chemical additive designed for use in ruthenium or black rhodium electroplating baths to enhance and deepen the dark color tone of the deposited metal layer. By adding this additive in controlled amounts, the coating achieves a deeper, more uniform black or dark anthracite appearance, ideal for decorative applications, modern design surfaces, and high-contrast multilayer plating systems. Applications This blackening additive is used for: Deepening the black or dark gray color of ruthenium and black rhodium coatings Fine color adjustment of dark electroplated finishes Improving uniformity and depth of the deposited layer Creating intense decorative effects on jewelry and accessories Use in tank, brush, and pen/plug plating It allows precise control of the final color without changing the base electrolyte. How the Blackening Additive Works (Simple Explanation) Ruthenium and black rhodium baths produce coatings whose final color depends on bath chemistry and operating parameters. The blackening additive modifies the electrochemical deposition process when added in defined quantities, resulting in a darker and more intense metal finish: Prepare the base bath: Operate the ruthenium or black rhodium electrolyte according to specifications. Add the blackening additive: Introduce the additive at the recommended dosage. Electroplating: Plate as usual; the deposited layer appears darker and more uniform. Fine adjustment: The final shade can be precisely adjusted by dosage and process settings. Advantages of Blackening Additive BMG-090.2M Intense black and anthracite color tones Improved visual uniformity of dark coatings Enables precise color tuning Compatible with existing ruthenium and black rhodium electrolytes Suitable for tank, brush, and pen plating Easy integration into existing plating processes Technical Parameters PropertyValue / RangeProduct typeBlackening additiveIntended useRuthenium and black rhodium electrolytesFunctionColor depth and intensity enhancementApplication methodAdded directly to plating bathCompatibilityTank, brush, and pen/plug platingColor effectDeeper black / dark anthraciteDosageProcess- and bath-dependentStorageCool, dry, tightly closedSafety classificationChemical additive – handle with care Note: Optimal dosage depends on bath chemistry, temperature, and desired color depth. Preliminary testing is recommended. Application Notes Add the blackening additive gradually while ensuring proper bath agitation. Perform test runs to determine the ideal concentration for the desired shade. Avoid overdosing, as this may affect coating uniformity. Maintain stable plating parameters for consistent results.
