  • Applications

    Diethoxyethyl succinate (CAS 26962-29-8) is the diester of succinic acid with two ethoxyethyl groups; in industry, it is primarily used as a plasticizer for polymers such as PVC and polyester resin systems, helping to increase softness, flexibility, and elasticity. It is also used as a solvent and processing aid in coatings, inks, and adhesives, providing solvency and processability enhancements for formulations. Additionally, it can serve as a synthetic intermediate for alkyd and polyester products, or as a plasticizer and binder-compatible component in composite systems. It is also considered a processing aid in coatings and adhesives, compatible with various binders and potentially improving formulation stability. Use and regulatory constraints should be determined by local regulations and specific formulations.
