Hydroxyethyl methacrylate is a colorless, transparent and flowable liquid, soluble in common organic solvents. Hydroxyethyl methacrylate is mainly used to modify resins and coatings. Acrylic resin with active hydroxyl group in side chain can be prepared by copolymerization with other acrylic monomers. It can be used for esterification and cross-linking reaction to synthesize insoluble resin and improve adhesion. It can be used as fiber treatment agent. It can react with melamine formaldehyde (or urea formaldehyde) resin and epoxy resin to produce two-component coatings. It can keep the mirror luster for a long time by adding it into the paint of high-grade car. It can also be used as adhesive for synthetic textiles and medical polymer monomer.
