  • Applications

    Longistyline C (CAS 64125-60-6) is used primarily as a solvent or co-solvent and as a processing aid in industrial formulations and cleaning formulations; it can act as a plasticizer and compatibility agent in polymers, coatings, and adhesives; it serves as an intermediate in organic synthesis; it may be evaluated as an additive to improve film formation and flexibility in coatings and inks; and it can function as a stabilizer or performance modifier in formulated polymer systems. Specific uses depend on product formulations and regulatory constraints.
