Tin Electrolyte 22 g/L – Professional Tin Plating Solution for Coatings Exceeding 1 mm
High-Performance Tin Plating Bath for Thin and Extremely Thick Tin Coatings
The ready-to-use Tin Electrolyte BMG-097M from Betzmann Galvanik is a professional electroplating solution designed for depositing high-quality tin coatings on electrically conductive surfaces.
With a tin concentration of 22 g/L, this electrolyte produces uniform tin deposits with a matt to satin finish. One of its outstanding features is its ability to achieve exceptionally high coating thicknesses of more than 1,000 microns (over 1 mm).
This makes the tin plating solution suitable not only for thin functional coatings but also for applications requiring the controlled build-up of very thick tin layers.
At a current density of 0.01 A/cm² and a temperature of 20 °C, the deposition rate is approximately 0.5 microns per minute with mild agitation.
The electrolyte provides a cathode efficiency of 100% under the specified reference conditions and produces deposits with very low internal stress.
A graphite electrode is used for this plating process.

Application and Processing
The tin electrolyte is suitable for electroplating electrically conductive workpieces and for the controlled deposition of thick tin coatings.
For optimum plating results, the following operating conditions are recommended:
Temperature: 18–25 °C
pH value: 3.6–4.0
Reference current density: 0.01 A/cm²
Electrode material: Graphite
Electrolyte agitation: Medium to vigorous
Filtration: Continuous filtration using a filter pump is recommended
Higher current densities can also be used. Longer anode operating times are possible when anode bags are not used. In these cases, continuous filtration of the electrolyte is essential.
Properties of the Deposited Tin Coating
The deposited tin coating has a matt to satin appearance. At thicknesses exceeding 20 µm, the surface develops an increasingly crystalline structure.
Additional deposit characteristics:
Very low internal stress
High cathode efficiency
White beta-tin (β-Sn) structure
Deposit density: 7.289 g/cm³
Hardness: 1.5 Mohs
Storage and Shelf Life
The tin electrolyte must be stored in a hermetically sealed container. The tin salt is sensitive to oxygen, so contact with atmospheric oxygen should be minimized to maintain product quality and stability.
Shelf life under proper storage conditions: approximately 1–2 years.
