Hydroxyethyl acrylate is the organic compound with the formula CH₂=CHCO₂CH₂CH₂OH. It is a colorless viscous liquid. The compound has dual functionality: a polymerizable acrylic and a hydroxy group. It is a monomer used to make emulsion polymers along with other monomers and the resultant resins are used in coatings, sealants, adhesives and elastomers and other applications.
