2-Hydroxyethyl methacrylate is mainly used for the modification of resins and coatings. Copolymerization with other acrylic monomers can produce acrylic resins with active hydroxyl groups in the side chains, which can undergo esterification and crosslinking reactions, synthesize insoluble resins and improve adhesion, and can be used as fiber treatment agents, etc. It reacts with melamine-formaldehyde (or urea-formaldehyde) resin, epoxy resin, etc. to make two-component coatings. Adding to the high-end car paint can maintain the mirror gloss for a long time. It can also be used as an adhesive for synthetic textiles and medical polymer monomers
