What is Tin(II) tetrafluoroborate?
Tin(II) tetrafluoroborate (CAS 13814-97-6) is an inorganic tin salt in aqueous solution for electrochemical and surface treatment processes.
Where is Tin(II) tetrafluoroborate used?
- Electrolytic baths: soluble source of stannous ions
- Electronics: electroplating baths depositing uniform tin coatings on printed circuit board traces and connector pins
- Electronics: tin-lead and pure tin plating in high-speed reel-to-reel operations
- Printing: production of tinned metal substrates for packaging
- Mining and metals: surface finishing lines with fluoroborate-based electrolytes offering improved bath stability
- It enables controlled tin deposition onto metal substrates during industrial manufacturing.
Good to know: Fluoroborate-based electrolytes offer higher current density tolerance than traditional sulfate systems. Quality control covers tin content and free acid levels.
Commercial specifications
- Packaging: drums and intermediate bulk containers
