Potassium Stannate Manufacturer & Supplier in India
Potassium Stannate is a white crystalline powder and one of the most important tin(IV) compounds used in industrial manufacturing. In alkaline tin electroplating, it is used as the tin source in potassium-based baths, which some platers choose for their higher solubility compared with sodium-based baths.
Beyond electroplating, Potassium Stannate serves as a flame retardant additive in polymer and textile applications, and as a weighting agent in the textile finishing industry. Its tin(IV) alkaline chemistry also makes it suitable for use in processes where Sodium Stannate would introduce unwanted sodium content into the bath or formulation. Our product is manufactured to meet the purity demands of all these end uses and is exported with full COA, MSDS, and compliance documentation.

What is Potassium Stannate Used For?
Potassium Stannate serves four distinct industrial sectors where its tin(IV) chemistry and solubility make it useful.
Electroplating
Alkaline Tin Plating Industries
Potassium Stannate is widely used to replace silver with tin in alkaline electroplating processes. The potassium-based alkaline bath produces smooth, uniform tin coatings on steel, copper, and aluminium substrates. It is used for alkaline tin plating in food packaging, electrical contacts, and corrosion protection applications.
Electronics & High-Precision Plating
Electronic Component Plating
Potassium Stannate baths are used to plate tin on components such as connector pins and lead frames. Suitability for a specific line should be confirmed with trial plating.
Fire Safety
Fire Retardant in Polymers & Textiles
Potassium Stannate is used as a halogen-free flame retardant additive in polymer compounds and textile finishing treatments. It works synergistically with other flame retardant systems to reduce the flammability of plastics, coatings, and treated fabrics.
Textile
Weighting Agent in Textile Industries
In the textile industry, Potassium Stannate has a long history of use as a weighting agent for silk and other natural fibres, adding body, weight, and drape to finished fabrics. It is also employed in selected dyeing and finishing processes where its alkaline tin chemistry assists colour development. The potassium form is preferred in some textile baths because it avoids sodium-related interference with certain dye chemistries.

Frequently Asked Questions
The chemical formula of Potassium Stannate is K₂SnO₃·3H₂O. The CAS number is 12125-03-0 and the molecular weight is 298.95 g/mol. It is a tin(IV) compound where tin is in the +4 oxidation state, and it forms a strongly alkaline solution when dissolved in water. Solubility in water is 110.5 g per 100 mL at 15°C.
The CAS number of Potassium Stannate (K₂SnO₃·3H₂O) is 12125-03-0. The molecular weight is 298.95 g/mol. Meghachem manufactures Potassium Stannate with a minimum Sn content of 39.00% and metal impurities below 100 ppm. A Certificate of Analysis confirming these parameters is provided with every shipment.
Potassium Stannate has three primary industrial uses. First, it is the main tin source in alkaline tin electroplating baths, widely used to replace silver with tin on metal substrates. Second, it serves as a flame retardant additive in polymer and textile applications. Third, it functions as a weighting agent in the textile industry for silk and other natural fibres.
Both Potassium Stannate and Sodium Stannate are used in alkaline tin electroplating baths, but they differ in key performance characteristics. Potassium Stannate is more soluble in water than Sodium Stannate, so potassium baths can be run at higher tin concentrations. Sodium Stannate is often chosen for general-purpose alkaline tin plating where cost matters most. The Sn content also differs: Sodium Stannate typically runs at 42% Sn minimum, while Potassium Stannate is at 39% Sn minimum because the potassium salt has a higher molecular weight (298.95 g/mol vs 266.73 g/mol), so tin makes up a smaller share of its mass.
Our standard specification is Sn Percentage at 39.00% minimum, Water Insoluble Matter below 500 ppm, Free Alkali below 1.5%, Chloride below 500 ppm, Sulfate below 200 ppm, Nitrate below 500 ppm, and Metal Impurities below 100 ppm. Solubility in water is 110.5 g per 100 mL at 15°C. A Certificate of Analysis is provided with every shipment and we can accommodate custom purity specifications on request for qualifying buyers.
Yes. We export Potassium Stannate to 25+ countries including Germany, Netherlands, Turkey, UAE, Oman, Indonesia, Vietnam, USA, Singapore, Malaysia, UK, and Japan.
