1,4-Butanediol diglycidyl ether is widely used as a crosslinking agent in the production of epoxy resins. It enhances the mechanical properties, thermal stability, and chemical resistance of the resins, making them suitable for coatings, adhesives, and composite materials. In the electronics industry, it is employed in encapsulating and insulating components due to its excellent dielectric properties. Additionally, it serves as a reactive diluent to adjust the viscosity of epoxy formulations, improving their processability. The chemical is also utilized in the modification of polymers and textiles to impart durability and water resistance. Its versatility makes it valuable in applications requiring strong, durable, and chemically resistant materials.
