  • Applications

    2-Butenoic acid, octyl ester (CAS 22874-79-9) is primarily used as a reactive monomer for acrylic polymers, enabling the production of flexible polyacrylates for coatings, paints, sealants, adhesives, and inks. It is a common component in UV-curable resin systems, where it acts as both a monomer and a reactive diluent to promote rapid cure and robust film formation. Additionally, it is employed in specialty polymer formulations to tailor mechanical properties such as flexibility, adhesion, and chemical resistance of adhesives and sealants used in electronics, automotive, and industrial manufacturing. It may also be incorporated into polyacrylate resins for coatings and plastics applications.
