REAXIS® E144 (Sodium Stannate), also known as Hexahydroxy Stannate or Sodium Stannate Trihydrate, is a Sn (IV)-based inorganic tin chemical. The standard crystalline grade of REAXIS® E144 contains approximately 44% tin. REAXIS® E144 is produced such that residual metal contaminates are controlled, thus resulting in a high-purity end product. Alternative grades to the REAXIS® E144 include liquid grades REAXIS® E144P-22 and Sodium Stannate, 30% and the higher-purity REAXIS® E144P. Alternatives to REAXIS® E144 would be the potassium grades REAXIS® E140 and REAXIS® E140P. REAXIS® E144 is present on a wide range of international regulatory lists, making it a great choice in new formulations.

REAXIS® E144 is used in a wide range of applications including surface finishing, stabilization of hydrogen peroxide, and electrolyte additives for battery applications. In surface finishing applications, REAXIS® E144 is used as an alkaline electroplating additive in high-speed plating operations given its ideal solubility. Related applications include the coating of automotive pistons and coin minting. REAXIS® E144 is used as a stabilizer for hydrogen peroxide via the complexation of destabilizing residual metals thus resulting in extended storage stability. REAXIS® E144 can be a in electrolytes in metal-air batteries to minimize and control electrode corrosion/passivation/fouling.
REAXIS® E144 has a reactivity characterized by its high tin content, species of tin (as Sn (IV) present, and solubility. Like all inorganic tins products produced by Reaxis, the concentration of the active tin species, versus the inactive forms, is maximized. In terms of functionality, REAXIS® E144 acts as both a good chelating agent for a wide variety of metals and an efficient tin metal plating agent.
Packaging
Storage
REAXIS® E144 should be stored in the original packaging. The container should be closed tightly after each use to maximize shelf life. This product does have the tendency to occasionally clump. This occurrence does not affect the quality/reactivity of the product.
