SODIUM HEXAHYDROXOSTANNATE (Na₂[Sn(OH)₆]) is an efficient and environmentally friendly alkaline tin source. It is mainly used in cyanide-free electroplating, flame retardant materials, and ceramic glazes
1.Environmental protection features
Completely free of cyanide, in line with modern environmental requirements
It can replace the traditional highly toxic cyanide tinning process
Wastewater treatment is relatively simple
2.Excellent electroplating performance
The coating is fine crystalline, uniform and bright – the plating solution has good stability and is not easy to decompose
– Fast deposition speed, suitable for high-speed electroplating
– Coating has strong adhesion and good corrosion resistance
3.Technological advantages
Wide operating temperature range (15-65℃)
High current efficiency (close to 100%)
The plating solution is easy to maintain
Suitable for electroplating of complex workpieces
4.Versatility
It can be used as a main salt or as an additive
Suitable for a variety of substrates (steel, copper alloys, etc.)
Tin coatings with different properties can be prepared
