Reaxis®  S50 - Stannous Chloride Solution

Stannous Chloride Dihydrate, frequently called stannous chloride and referred to as SnCl2, is a versatile high metal content stannous inorganic tin that is used in several reactions and specialty chemical applications, including use as a reducing agent. REAXIS® S50 is one of our family of liquid grades of the primary solid grade, REAXIS® C154. REAXIS® C154 is produced to the highest standards, utilizing high- purity tin metal while minimizing stannic and maximizing stannous content. REAXIS® S50 is a stable liquid grade containing approximately 50% of REAXIS® C154 and 25% active stannous tin. Other liquid grades include, REAXIS® S45, REAXIS® S72 and REAXIS® S25. REAXIS® S50 is present on a wide range of international regulatory inventories, making it an ideal choice for global formula development.

Applications

Common end-use chemistries and applications for REAXIS® S50 include: esterifications, personal care, surface finishing, oil well stimulation, as an acidizing additive, corrosion inhibition, and glass as a silver mirroring and color modifier. As a reducing agent, REAXIS® S50 finds diverse applications and benefits in various applications such as those requiring the reduction of silver used for mirror coatings and the reduction of iron needed in oil & gas well stimulations. This reduction functionality is commonly used in water treatment applications. This is a versatile inorganic tin chemical with applications across many markets and applications, from batteries and glass to plating and reducing agents.

Reactivity

The main reactivity attribute of REAXIS® S50 would be in its reduction of a wide range of metals. This electron transfer makes REAXIS® S50 an ideal additive where toxic metal impurities are present and need to either be reduced or separated out. This type of reactivity would be a function of stannous tin content and thus, the various liquid grades of stannous chloride would be differentiated here due to the differences in tin content. 

Package & Storage

  • 30 gal plastic drum, 375 lbs net
  • 275 gal tote, 3200 lbs net

REAXIS® S50 should be stored in the original packaging.  The container should be closed tightly after each use to maximize shelf life. Characteristic of most inorganic tins Sn(II), the primary cause of instability would be oxidation, where the signs of oxidation would be the yellowing of the white crystals.
