Furfuryl glycidyl ether is widely used as a reactive diluent in epoxy resin systems. It helps reduce the viscosity of epoxy formulations, making them easier to process and apply, particularly in coatings, adhesives, and composites. Its incorporation enhances flexibility and impact resistance in cured epoxy products. Additionally, it is utilized in the production of specialty polymers and as a modifier to improve the mechanical and thermal properties of materials. Its bio-based origin also makes it a sustainable choice in green chemistry applications.
