  • Applications

    2-ethylhexanoic acid tin(II) salt (CAS number: 301-10-0) is used mainly in polymer processing as a tin-based stabilizer and catalyst. In plastics, it acts as a primary heat stabilizer for PVC formulations, helping prevent color formation and degradation during processing. In polyurethane chemistry, it functions as a catalyst for polymerization and for formulations such as coatings, foams, and adhesives, and may be employed as a processing catalyst in other resin systems. Additionally, it serves as an intermediate in the synthesis of other tin-based stabilizers and catalysts for polymer processing. In coatings and inks, it may be used to facilitate curing of polyurethane components or as part of tin-catalyzed formulations. Use is subject to local regulations and formulation limits.
