Glycidyl phenyl ether is widely used as a reactive diluent in epoxy resin formulations, enhancing flexibility and reducing viscosity for easier application in coatings, adhesives, and composites. It is also employed in the production of electrical insulation materials due to its excellent dielectric properties. In the electronics industry, it serves as a key component in encapsulants and potting compounds, providing protection to sensitive components. Additionally, it finds application in the synthesis of specialty chemicals, including surfactants and polymers, due to its epoxy functionality and ability to undergo ring-opening reactions. Its versatility makes it valuable in industries requiring durable and high-performance materials.
