2-Phenylethyl acrylate is primarily used as a reactive monomer in polymer synthesis, enabling the production of specialty adhesives, coatings, and sealants with enhanced flexibility, adhesion to various substrates, and improved durability. Its structure facilitates copolymerization with other monomers to customize polymer properties, particularly for pressure-sensitive adhesives in tapes and labels. The acrylate functionality supports its use in radiation-curable formulations for rapid UV curing. It also acts as a crosslinking agent to enhance chemical resistance and in controlled release systems. Additionally, it is employed in the fragrance and cosmetics industries as a fixative to prolong scent retention in perfumes, beauty products, and related formulations.
