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. Also utilized in the modification of polymers and as a crosslinking agent in specialty resins. Its hydrophilic nature makes it suitable for applications requiring water solubility or compatibility with polar substances.
