Used primarily as a reactive monomer in the production of polymers and copolymers, 2-Hydroxyethyl acrylate is widely applied in the formulation of adhesives, coatings, and sealants due to its ability to improve adhesion, flexibility, and cross-linking. Its hydroxyl group enables further chemical modification, making it valuable in UV-curable systems such as inks, varnishes, and dental materials. It is also utilized in the manufacture of pressure-sensitive adhesives and textile finishes. In personal care products, it serves as a building block for thickeners and film-forming agents in cosmetics. Additionally, it finds use in hydrogels for medical applications and contact lenses because of its hydrophilic nature and biocompatibility.
