Used as a reactive diluent in epoxy resin systems to reduce viscosity while maintaining reactivity. The naphthyl group contributes to enhanced thermal and chemical resistance. Enhances flexibility and adhesion in coatings, adhesives, and composite materials. Commonly employed in the formulation of electronic encapsulants and insulating materials due to its good electrical properties. Also utilized in chemical synthesis as a building block for introducing naphthyl and epoxide functionalities in specialty compounds.
