Applications
Common end-use chemistries and applications for REAXIS® C154 include: esterifications, thermoplastic elastomers, personal care, surface finishing, oil well simulation (acidizing additive), corrosion inhibition, and glass (silver mirroring and color modifier). As a catalyst, REAXIS® C154 plays a crucial role in the esterification process, which is fundamental to the production of various esters. Stannous chloride dihydrate, as a reducing agent, finds diverse applications and benefits in various industries. As a plating agent in electroplating applications, it serves as a primary reducing agent to deposit metal layers, such as silver or tin, onto substrates. By donating electrons, REAXIS® C154, stannous chloride dihydrate, reduces the metal ions to their corresponding metallic forms, which adhere to the substrate’s surface. This process results in a uniform, thin coating that improves the final product’s appearance, durability, and corrosion resistance.
Reactivity
As is typical of most organotin and inorganic tin catalysts, the specific ligand in addition to the tin metal concentration contributes a major influence on overall reactivity. Due to its high tin concentration and small ligand, REAXIS® C154 is a very active esterification catalyst with comparable reactivity to common organotin catalysts such as dibutyl and monobutyl tin oxides. Given its inorganic nature, REAXIS® C154 is stable at high reaction temperatures that are typical of many esterification reactions. Due to the presence of chlorides, color formation may be an issue with some ester formulations. If the presence of residual moisture in REAXIS® C154 is deemed to be an issue with the catalysis of esters, REAXIS® C162 would be an ideal, moisture-free alternative.
Package & Storage
- 55 lb (25 kg) plastic pail
REAXIS® C154 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® C154 has a low melting point (38C)and is hygroscopic.
