Overview
REAXIS® E10, also known as Sodium Stannate Trihydrate or Sodium Hexhydroxostannate, is a Sn (IV)-based inorganic tin chemical. REAXIS® E10 is a stable liquid version characterized by optimum sodium stannate content ranging from 118 to 130 g/L. Our manufacturing process incorporates high quality raw materials, minimizing residuals and enhancing overall product quality. Residual metal contaminants (Pb, Fe, Cu, Ni, Sb, Bi) are minimized. Alternative grades of REAXIS® E10 include crystal grades, REAXIS® E144P and REAXIS® E144. Alternatives to sodium-based stannates include the potassium stannate grades, REAXIS® E140 and REAXIS® E140P. Liquid grades of both sodium and potassium stannates can be manufactured based on customer-defined specifications and solubility limitations. REAXIS® E10 is a commonly used additive in a wide range of applications, including use as a complexing agent or reducing agent, and is present on many international inventory lists.

Applications
REAXIS® E10 is a stannate used as an additive in a wide range of applications including surface finishing, the stabilization of hydrogen peroxide, use as a reducing agent, use as a complexing agent, and glass manufacturing. In surface finishing, REAXIS® E10 is used as an alkaline electroplating additive in high-speed plating operations, coin minting and electroless processes such as piston plating. Additionally, it is used for hydrogen peroxide stabilization, as a mordant for dyeing processes, various glass manufacturing processes, and as an electrolyte additive in batteries. Niche applications involve chemical syntheses requiring a stable tin source and water treatment applications demanding caustic solutions.
Reactivity
The diverse applicability of sodium stannate stems from its fundamental compatibility with the chemistries employed in glass manufacturing, surface finishing, and redox reactions. REAXIS® E10 has a reactivity characterized by its high tin content and its inorganic tin (as Sn(IV)) nature. Like all inorganic tin products produced by Reaxis, the concentration of the active tin species, versus the inactive forms, is maximized. In terms of functionality, REAXIS® E10 acts as both a good chelating agent for a wide variety of metals and an efficient tin metal plating agent. REAXIS® E10 offers rapid reactivity and efficient ion movement, leading to consistent quality and faster processing times.
Package & Storage
