Yellow Chromating – Yellow Passivation (SW10019.2) Chromating / Passivation for Aesthetic Finishing and Corrosion Protection of Zinc-Plated Surfaces Short Description The Yellow Chromating / Yellow Passivation SW10019.2 is a chemical solution for the non-electrolytic treatment of zinc-plated metal parts, producing a yellow to gold-colored protective and passivating layer. This layer enhances corrosion resistance, improves the appearance of zinc-plated parts, and mimics the look of traditional yellow chromating—without the use of highly toxic hexavalent chromium chemicals. The treatment is simple to perform in a dip bath without electricity and is suitable as a finish after galvanic zinc plating. Applications Yellow Chromating is used to: Enhance zinc-plated surfaces Provide aesthetic coloring in yellow to gold shades Improve corrosion resistance of metal parts Finish after galvanic zinc plating or accessory zinc plating Ideal for hobbyists, workshops, restorers, and industrial use The resulting color resembles the classic “brass-look” of traditional chromating with a slight iridescent effect—in an environmentally safer formulation. How it Works (Simple Explanation) Pre-treatment: Ensure the metal part has a sufficient zinc layer (≥ 2 µm). Dip: Immerse the zinc-plated part into the yellow chromating bath. Chemical Reaction: Within minutes, a yellow passivation layer forms as part of the zinc surface is chemically converted. Rinse: After achieving the desired color, rinse thoroughly with distilled water. The process can be stopped or repeated depending on whether a lighter yellow or more intense gold tone is desired. Advantages Simple, non-electrolytic application – no power supply or equipment required Chromium(VI)-free, safer and more environmentally friendly than traditional chromating Improves corrosion resistance of zinc-plated surfaces Produces aesthetic yellow to gold color with slight iridescence Ideal for finishing and restoration, e.g., old-timer parts Technical Information PropertyDetails / InformationProduct typeYellow Chromating / Yellow PassivationApplicationNon-electrolytic, dip bathSuitable forZinc-plated metal partsColorYellow to gold, slightly iridescentRequired zinc thickness≥ 2 µm recommendedImmersion timeA few minutes (depending on desired effect)TemperatureRoom temperatureChromium(VI)-freeYes (based on less hazardous Chromium(III)) Practical Instructions Ensure the zinc layer is sufficiently thick (≥ 2 µm), especially for self-zinced parts. Dip: Immerse the parts for several minutes—the exact duration controls color intensity. Rinse: Once the desired tone is reached, rinse thoroughly with distilled water and allow to dry. Color adjustment: Repeat dipping to achieve variations from light yellow to gold. Safety Instructions Even though the solution is Chromium(VI)-free and less toxic than traditional chromating, it is a chemical treatment: Wear gloves, safety glasses, and protective clothing Avoid contact with skin and eyes Rinse immediately with water in case of contact Use only in well-ventilated areas Do not ingest; keep out of reach of children Conclusion The Yellow Chromating / Yellow Passivation SW10019.2 provides a simple, non-electrolytic way to enhance the appearance of zinc-plated metal parts while improving corrosion protection. Its modern, Chromium(VI)-free formula makes it a safe, environmentally friendly alternative to traditional chromating methods, ideal for hobbyists, restorers, workshops, and professional galvanic applications.

Zinc Electrode Ø 6 mm (BMG‑Zinc Electrode) Short Description The Zinc Electrode Ø 6 mm is a high‑purity zinc anode (Zn 99.95 %) designed for electroplating applications where controlled zinc ion release is essential. It promotes uniform, corrosion‑resistant zinc layers and is suitable for bath, pen, and pad plating setups. Product Description This zinc electrode is crafted from unalloyed, high‑purity zinc with a diameter of 6 mm and a practical length of approximately 100–120 mm. Its composition and geometry make it suitable as a standard anode for a range of electrochemical processes, including zinc plating and ion migration studies.  During plating, zinc dissolves in a controlled manner, helping to maintain bath composition and balance metal content, which in turn leads to reliable, homogenous deposit formation. It serves as a sacrificial anode, continuously replenishing the electrolyte with zinc ions while the workpiece is plated. Typical Applications Electroplating and zinc coating operations Bath, pen and pad plating techniques Corrosion protection layers for iron, steel or copper alloys Electrochemical experimentation and teaching Practical use in laboratories, workshops, and production Key Benefits High‑purity zinc (99.95 %) for consistent ion release Efficient plating bath regeneration Versatile use across galvanic methods Uniform coating formation Standard Ø 6 mm size fits most electrode holders  Usage Instructions Preparation: Clean and degrease all surfaces before plating to ensure good adhesion. Setup: Mount the zinc electrode as the anode (positive terminal) and connect the workpiece as the cathode (negative terminal). Electroplating: Operate at appropriate voltage and current density for zinc plating; low voltages and moderate currents typically yield uniform finishes. Maintenance: Over time the electrode surface may change — periodic cleaning or replacement keeps performance optimal. Conclusion The Zinc Electrode Ø 6 mm is a reliable, easy‑to‑use component for zinc electroplating and corrosion‑resistant coatings, suitable for both hobby and professional applications, offering excellent process stability and consistent results.

Zinc Anode / Plate Electrode (SW10071) Short Description The Zinc Anode / Plate Electrode is a flat sacrificial anode made from high-purity zinc (Zn ≥ 99.8 %), designed for electroplating processes that require uniform, protective zinc coatings. It supplies zinc ions steadily into the electrolyte, promoting stable plating conditions and consistent deposit quality.  Product Description This plate electrode is made from high-purity zinc and features a flat, broad geometry (approx. 50 × 80 mm for the M size) with a thickness of about 0.7 mm, making it suitable for plating larger surface areas evenly. As a sacrificial anode, zinc dissolves in a controlled manner, helping to maintain the metal content of the bath and provide stable plating conditions.  The large active surface makes this electrode particularly suitable for bath electroplating with zinc electrolytes, ensuring uniform current distribution and improved coating quality. Typical Applications Electroplating of zinc for corrosion protection Bath plating for decorative or functional zinc finishes Plating of larger components requiring even coverage Workshop, laboratory, and educational electroplating processes Key Benefits High-purity zinc (≥ 99.8 %): supports clean, reproducible results Broad plate design: improves current distribution across surfaces Ideal for zinc electrolyte baths: enhances plating consistency Controlled electrolyte regeneration: maintains bath composition Simple to integrate: suitable for various electroplating setups Usage Instructions Preparation: Thoroughly clean and degrease the workpiece; activate if required. Placement: Position the zinc plate electrode as the anode (positive terminal) in the electrolyte, with the workpiece as the cathode. Plating: Set current and voltage according to the specific zinc electrolyte — typically low volt ranges are used. Maintenance: Clean the electrode periodically to remove oxide buildup and maintain performance. Conclusion The Zinc Anode / Plate Electrode is an efficient sacrificial anode designed for consistent and uniform zinc electroplating. Its large active surface and high material purity make it suitable for hobby, workshop, and professional electroplating applications alike.

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.
