  • Applications

    Isopropyl crotonate (E) is used primarily as a reactive monomer or reactive diluent in UV-curable coatings, inks, and adhesives; it also serves as an intermediate in organic synthesis for fine chemicals and specialty esters; in perfumery it can function as a fragrance ingredient or aroma chemical; in industrial formulations it can act as a solvent or processing aid for coatings and related systems; and it can serve as a precursor to other crotonate esters employed in polymer and coatings applications.
