Reaxis® C154S
REAXIS® C154S (Stannous Chloride Dihydrate), is a versatile high metal content stannous inorganic tin that is used in applications where a free-flowing solid is required. REAXIS® C154S consists of stannous chloride dihydrate (REAXIS® C154) combined with silica and is processed to ensure a free-flowing solid that acts to minimize the negative effects of temperature and hygroscopicity. Stannous chloride dihydrate is produced to the highest quality standards, meeting A.C.S. specifications and maximizing stannous tin content while minimizing stannic tin content. Stability/free-flowability can be enhanced via blends with various products including silica, talc, and numerous solid resins. Similar products include REAXIS® C154T, which is the variant with talc, REAXIS® C154P which contains polypropylene, and REAXIS® C154S+. Specialty blends and related products with tailored particle sizes can be offered upon request. REAXIS® C154S is present on most international regulatory lists as commercial use-compliant.

Applications
Common end-use chemistries and applications for stannous chloride dihydrate include: esterifications, thermoplastic elastomers, personal care, surface finishing, oil well simulation (acidizing additive), corrosion inhibition, and glass (silver mirroring and color modifier). REAXIS® C154S is primarily used in hybrid thermoplastic elastomers formulations, specifically in the production of EPDM and polyethylene-based thermoplastic vulcanizates (TPVs). Other applications include personal care products and use as a reducing agent. REAXIS® C154S is of the inorganic tin family of tin chemicals and is an ideal candidate, in select chemistries and formulations, as an alternative to more regulatory controlled organotins.
Reactivity
Due to its high tin concentration, small ligand, and inorganic Sn (II) nature, REAXIS® C154S is a very active catalyst and reducing agent. Given its inorganic tin nature, REAXIS® C154S is stable at high reaction temperatures typical of many reactions. In addition, REAXIS® C154S is characterized by a narrow particle size distribution resulting in ideal blending with other solid raw materials.
Package & Storage
Packaging
- 44 lb (20 kg) plastic pails
Storage
REAXIS® C154S 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. Additionally, REAXIS® C154S has a low melting point (38C) and is hygroscopic.
