Blue Chromating – Blue Passivation (SW10025.1) Chemical Passivation and Surface Finishing for Zinc-Plated Metal Parts Short Description The Blue Chromating / Blue Passivation SW10025.1 is a chemical solution for the non-electrolytic treatment of zinc-plated metal parts, producing a blue to dark blue protective passivation layer. This layer provides effective corrosion protection, enhances the appearance of zinc-plated parts, and gives a professional metallic blue finish. The treatment is simple to apply in a dip bath without electricity and is suitable as a finish after galvanic zinc plating. Applications Blue passivation is used for: Surface finishing of zinc-plated parts Aesthetic blue to dark blue coloring Corrosion protection and surface stabilization Finishing after galvanic zinc plating Suitable for hobby, workshops, restoration, and industrial use The color ranges from light blue to deep metallic blue, providing a high-quality visual finish. How it Works (Simple Explanation) Preparation: Ensure the metal part has a sufficient zinc layer (≥ 2 µm). Dip: Immerse the zinc-plated part into the blue chromating bath. Chemical Reaction: Within minutes, a blue passivation layer forms on the surface. Rinse: After reaching the desired color, rinse the part with water and dry it. The color intensity can be adjusted by varying the immersion time.

Tin‑Zinc 70/30 Electrolyte BMG‑100 Eco‑Friendly Tin‑Zinc Alloy Plating Solution for Durable Metal Coatings Short Description The Tin‑Zinc 70/30 Electrolyte BMG‑100 is a specialized electroplating solution designed to deposit a tin‑zinc alloy layer with approximately 70 % tin and 30 % zinc. This alloy coating offers excellent corrosion resistance, solderability, and ductility, while serving as an environmentally friendlier alternative to cadmium plating.  Applications This tin‑zinc alloy electrolyte is suitable for: Alloy plating with tin and zinc for protective and functional layers Corrosion protection on ferrous and non‑ferrous metals Base coatings or primers before further plating steps Functional plating for joint and mechanical components Applications that require good solderability and flexibility How It Works (Simple Explanation) Tin–zinc electroplating uses an electrical current to reduce tin and zinc ions from the electrolyte onto the surface of the part being plated. The deposited alloy forms a uniform, adherent coating that combines the beneficial properties of both metals. Benefits of Tin‑Zinc 70/30 Alloy Plating Environmentally friendlier alternative to toxic cadmium plating  Excellent corrosion resistance for demanding environments High solderability — ideal for assembly and electronics Good ductility for flexible components Even coating thickness, even in recessed areas Typical Properties PropertyValue / RangeElectrolyte typeTin‑zinc alloy plating solutionAlloy ratioapprox. 70 % tin / 30 % zincCoating finishSilver‑white to matte grey (polishable)Corrosion protectionVery goodSolderabilityExcellentDuctilityHighLayer uniformityGood in recessed and complex shapes Practical Application Notes Preparation: Clean and degrease surfaces thoroughly. Plating: Operate the electrolyte with suitable anodes such as zinc or inert materials. Gentle agitation enhances uniform deposition. Post‑Treatment: Rinse plated parts and dry thoroughly. Polishing can enhance final appearance. Safety Information Wear protective gloves, goggles, and appropriate clothing Avoid contact with skin and eyes Rinse immediately with water if contact occurs Use only in well‑ventilated areas Do not ingest; keep out of reach of children Dispose of chemical waste according to local regulations Conclusion The Tin‑Zinc 70/30 Electrolyte BMG‑100 delivers durable, corrosion‑resistant alloy coatings with excellent mechanical and functional properties. Its combination of environmental friendliness, solderability, and performance makes it an ideal choice for protective and functional electroplating applications.

Sleeve - Swab - Anode fabric pad - Anode covers, thick, multi-layered - Replacement covers for pad electroplating from Betzmann Galvanik This thick, very robust anode fabric pad consists of several layers of fabric sewn together and is ideal for coating any surface. It does not wear out so quickly, especially on rough or coarse surfaces. At the lower end there are 2 insertion holes for the anode rod up to 6mm (for 8mm you can enlarge the holes with scissors or a knife. If this has already worked its way through the fabric at the top, you can continue to use the anode fabric pad by inserting it into the other insertion hole. Please soak the pad thoroughly before use, otherwise it will not conduct. Scope of delivery: 1 piece!

How does zinc plating work? (simple explanation) In galvanic zinc plating, zinc is deposited onto a metal surface using direct electrical current: The workpiece is thoroughly cleaned, degreased and derusted It is connected as the cathode (negative pole) A suitable zinc or graphite anode is connected as the positive pole When current is applied, zinc ions migrate from the electrolyte and form a protective zinc coating on the surface Proper surface preparation is essential to ensure good adhesion and long-lasting corrosion protection.

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.
