2-Hydroxyethyl methacrylate, commonly abbreviated as HEMA, belongs to functional acrylic monomers with dual reactive groups of hydroxyl and vinyl. It serves as an indispensable foundational raw material to synthesize poly(2-hydroxyethyl methacrylate), also known as PHEMA, alongside a full range of its modified derivatives.
The polymer PHEMA formed after HEMA polymerization boasts outstanding biocompatibility, hydrophilicity and soft texture, making it an ideal biomedical base material extensively adopted for manufacturing various water-swelling hydrogel medical supplies. Beyond medical fields, HEMA enjoys broad industrial applicability across multiple downstream sectors. It acts as a core monomer for soft contact lenses, and can also be formulated into high-performance coatings, strong bonding adhesives and resin modification additives. Additionally, it works as a key component in UV-curable photosensitive resins and specialized surface treatment agents for paper manufacturing, covering diverse fine chemical processing scenarios.

Product Application of 2-Hydroxyethyl methacrylate (CAS#868-77-9)
2-Hydroxyethyl methacrylate (HEMA) is a classic hydroxyl-containing acrylic monomer with outstanding photopolymerization activity, which serves as a core functional raw material for various UV curable printing inks and high-gloss UV coatings. It can effectively improve the hydrophilicity, adhesion and flexibility of coating films, and is well-matched with most photoinitiator systems.
Apart from light-curing materials, this monomer has broad downstream utilization in multiple consumer and medical industries. It is a key ingredient for high-strength industrial adhesives, cosmetic artificial nail gel systems, dental restoration materials and high-bright surface lacquers. Within dental material manufacturing, HEMA stands as one of the primary volatile acrylate monomers alongside methyl methacrylate, widely relied on for its good blending performance with dental resin substrates.
Moreover, it acts as a vital co-monomer for synthesizing high-performance polymer substrates. The resultant polymers are widely applied in fabricating comfortable, durable dental prosthetics. In the construction sector, HEMA is also formulated into special resin slurries for geotechnical grouting, which helps reinforce ground structures and seal underground cracks.
