Used as a reactive diluent in epoxy resin systems to reduce viscosity and improve workability without sacrificing performance. Enhances flexibility and impact resistance of cured epoxy formulations. Commonly applied in coatings, adhesives, sealants, and composite materials where improved toughness and adhesion are required. Its hydrophilic nature also aids in water-based epoxy systems, promoting stability and dispersion. Frequently utilized in specialty applications such as electronics encapsulation, flooring systems, and construction materials due to its ability to modify mechanical properties and extend pot life. Additionally, due to its biocompatibility from the polyethylene glycol chain, it is employed in pharmaceutical applications as a crosslinker or molecular linker in drug delivery systems and in biomaterials research for creating structures compatible with the human body, such as hydrogels for tissue engineering.
