2-Phenoxyethyl acrylate

2-Phenoxyethyl acrylate (CAS 48145-04-6) is a monofunctional reactive acrylate monomer, commercially available under trade names including SR 339, Ageflex PEA, Viscoat 192, and Chemlink 160, and commonly abbreviated as PO-A. It carries no assigned E-code and is classified under HS code 29161290.

In UV-curable coatings and radiation-cured adhesives, PO-A acts as a reactive diluent that lowers formulation viscosity while incorporating directly into the polymer network upon cure, avoiding the volatile losses associated with conventional solvents. Its phenoxy group contributes internal plasticisation to the cured film, improving flexibility and substrate adhesion in printing inks and packaging laminates.

PO-A is supplied as a clear liquid and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm supplier SDS documentation, inhibitor content, and storage conditions when specifying grades for photopolymer or pressure-sensitive adhesive applications.
