Tin Electrolyte BMG‑097

Versatile tin plating solution for corrosion protection and surface finishing


Short Description

The Tin Electrolyte BMG‑097 is a ready‑to‑use plating solution for electroplating tin onto conductive metals. It produces a uniform, protective tin layer that enhances corrosion resistance, improves surface solderability, and can be polished to a bright finish.
This versatile tin plating solution is suitable for hobby, workshop, and professional applications — from cookware to high‑end electronics. 


What is this tin electrolyte used for?

This tin electrolyte can be applied to:

  • Protect metal surfaces from corrosion and wear

  • Tin‑plate screws, fasteners, and components for improved durability

  • Improve solderability in electronics or plumbing without flux

  • Provide a decorative satin to polished surface finish

  • Serve as a surface finish on copper, nickel, palladium, cobalt, or thin gold layers for enhanced properties 

The electrolyte is valued for its low toxicity finish and is even suitable for applications like cookware plating. 


How does tin electroplating work? (simple explanation)

Tin electroplating uses electrical current to deposit tin from the electrolyte onto a metallic workpiece:

  1. The workpiece must be cleaned and degreased before plating.

  2. It is connected as the cathode (negative pole) in the plating circuit.

  3. A suitable tin or graphite anode is used as the positive pole.

  4. When the current flows, tin ions are reduced at the surface and form a tin coating.

This coating provides a uniform protective layer that is easy to polish and improves surface performance. 


Advantages of Tin Electrolyte BMG‑097

  • Produces satin to semi‑matte tin finishes that can be polished to shine 

  • Improves solderability without the need for flux

  • Suitable for use on a variety of substrates: copper, nickel, palladium, cobalt, thin gold layers 

  • Air‑sensitive formulation allows excellent results when stored correctly 

  • Easy to integrate into tank plating or brush/pen plating techniques

Practical Application Notes

Air Sensitivity:
The tin electrolyte is sensitive to oxygen. When not in use, keep the cap tightly closed and minimize air exposure in the bottle — e.g., by adding glass beads or storing in a sealed syringe — to prevent solution degradation

Bath Filtration:
For tank plating, continuous filtration is recommended if anode bags are not used. 

Polishing:
After plating, the tin deposit can be polished with suitable compounds (e.g., Ultra or Ultrafein from Betzmann Galvanik) to achieve a bright finish

Tin electroplating solutions contain acidic components and tin salts and should be handled with appropriate safety measures:

  • Wear chemical‑resistant gloves, eye protection and protective clothing

  • Avoid contact with skin or eyes

  • Rinse thoroughly with water if contact occurs

  • Use only in well‑ventilated areas

  • Do not inhale vapors or aerosols

  • Keep out of reach of children

The product is classified as an irritant under the EU CLP regulation.

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.
