4-Hydroxybutyl acrylate glycidyl ether is primarily utilized in the formulation of specialty adhesives and coatings due to its dual functional groups, which enhance adhesion and cross-linking properties. It is commonly incorporated into UV-curable coatings, providing excellent flexibility, durability, and resistance to chemicals and weathering. In the adhesive industry, it improves bonding strength and thermal stability, making it suitable for applications in automotive, electronics, and construction. Additionally, it is used in the production of reactive diluents for epoxy resins, reducing viscosity while maintaining performance. Its ability to copolymerize with other monomers also makes it valuable in creating tailored polymers for specific industrial needs.
