2-Hydroxyethyl acrylate (Cat No.:R070645) is a bifunctional monomer with the molecular formula C5H8O3, featuring both a polymerizable acrylate group and a reactive hydroxyl group. It is a clear, colorless liquid commonly used in the production of coatings, adhesives, sealants, and elastomers. The acrylate group enables free-radical polymerization, while the hydroxyl group allows for crosslinking and further chemical modification. HEA imparts flexibility, adhesion, and chemical resistance to polymers. Due to its versatility and reactivity, it is valuable in both industrial and biomedical applications, including hydrogels, dental materials, and surface treatments.
