Glycerol triglycidyl ether is widely used as a reactive diluent and crosslinking agent in epoxy resin formulations. It enhances the flexibility and adhesion properties of epoxy coatings, making them suitable for applications in paints, adhesives, and composites. Its trifunctional structure allows it to improve the thermal and chemical resistance of cured epoxy systems, which is beneficial in industrial coatings and electronic encapsulation. Additionally, it is utilized in the production of water-based epoxy resins, offering environmental advantages by reducing volatile organic compound (VOC) emissions. Its compatibility with various curing agents also makes it a versatile component in advanced material engineering.
