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. Safety Information Blackening additives contain active chemical substances and must be handled with care: Wear protective gloves, safety goggles, and suitable clothing Avoid skin and eye contact Rinse immediately with water in case of contact Use only in well-ventilated areas Do not ingest; keep out of reach of children Dispose of according to local chemical waste regulations Conclusion The Blackening Additive for Black Rhodium / Ruthenium BMG-090.2M is an effective solution for intensifying dark electroplated finishes. It allows precise control over black and anthracite tones while maintaining the original plating process. Ideal for jewelry, accessories, and decorative design surfaces, this additive delivers deeper, more uniform colors and enhances the overall visual quality of black rhodium and ruthenium coatings.

Black Rhodium Electrolyte BMG‑088.2 Decorative Black Rhodium Electrolyte for Dark Anthracite‑Gray Rhodium Coatings Short Description The Black Rhodium Electrolyte BMG‑088.2 is a ready-to-use electroplating solution for creating dark anthracite-gray, decorative rhodium coatings on conductive metal surfaces. The solution operates at room temperature, reducing the need for additional heating and making it particularly user-friendly. The deposited layers are uniform, color-stable, and wear-resistant, making it ideal for decorative applications in jewelry, eyewear, accessories, and high-end metal components. Applications Black rhodium plating is used for: Decorative coatings with a dark metallic effect Surface finishing for jewelry and eyewear Design and fashion components requiring a premium finish Two-tone plating effects in combination with lighter metals Applications requiring a strong, dark gray rhodium appearance This process provides a consistent, anthracite-gray decorative finish with the typical durability of rhodium plating. How Does Black Rhodium Work? (Simple Explanation) Black rhodium plating is an electrolytic process: Surface Preparation: Thoroughly clean, degrease, and optionally activate the workpiece. Electroplating: Connect the part as the cathode (negative pole); use a suitable anode, such as platinum-coated titanium. Deposition: Applying direct current causes rhodium ions to reduce and form a dark, uniform rhodium layer. Finish: Rinse and dry the plated parts to reveal the even anthracite-gray surface. The process is simple to handle and suitable for tank plating, brush plating, and pen plating. Benefits of Black Rhodium Electrolyte Dark anthracite-gray, uniform rhodium layers High wear resistance and color stability Decorative finish for jewelry, eyewear, and accessories Operates at room temperature, no heating required Easy bath handling and user-friendly Suitable for hobby, workshop, and professional electroplating Metals that can be rhodium-plated directly (with a clean, activated surface):Silver (Ag) – very suitableoften directly Gold (Au) – no problemPlatinum (Pt) – no problemPalladium (Pd) – well suitedPalladium alloys – usually possible directlyTechnical Parameters PropertyValue / RangeElectrolyte typeBlack Rhodium ElectrolyteRhodium contentapprox. 2.0 g/LpH< 1 (acidic)Density1.02–1.07 g/cm³Voltageapprox. 2–3 VTemperature20–27 °CCurrent density1.0–1.5 A/dm²Anode materialPlatinum-coated titanium or mixed oxideExposure time1–5 minutes (2 minutes standard)Deposition rate6–8 mg/A·minLayer thicknessup to 0.5 µmHardness300–370 HVLayer densityapprox. 10.5 g/cm³ Practical Application Tips Preparation: Clean, degrease, and optionally activate surfaces to ensure good adhesion and uniform coverage. Electroplating: Maintain recommended bath parameters and ensure proper anode-cathode distance. Post-treatment: Rinse thoroughly with clean water and gently dry. Darker shades: Adding a small darkening additive can deepen the black effect. Safety Information Wear chemical-resistant gloves, safety glasses, and protective clothing Avoid contact with skin and eyes Rinse immediately with water if contact occurs Work only in well-ventilated areas Do not ingest; keep out of reach of children The solution is strongly acidic and oxidizing; handle with care Conclusion The Black Rhodium Electrolyte BMG‑088.2 produces dark anthracite-gray rhodium coatings that combine decorative appeal with high wear resistance and ease of use. Operating at room temperature and suitable for tank, brush, and pen plating, this electrolyte is ideal for hobbyists, workshops, and professional applications. Its dark, uniform finish is perfect for jewelry, eyewear, accessories, and design items requiring a modern black rhodium appearance.
