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

Anode sleeve fuzzy

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.

Zinc Electrode

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 Plate Electrode

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.
