  • Applications

    Neopentyl glycol diglycidyl ether (CAS 17557-23-2) is an epoxy-functional monomer used primarily as a reactive diluent and crosslinking component in epoxy formulations, enabling lower viscosity and improved flexibility in cured networks. In practice, it is commonly used in coatings and inks to adjust rheology and enhance adhesion, in adhesives to improve toughness and chemical resistance, in polymers and epoxy resins as a modification or precursor for new resin grades, in electronics applications for encapsulation/potting and as a component in laminates, and in UV-curable coatings as a reactive diluent to reduce viscosity while contributing to cure. It is also employed in fiber-reinforced composites to tailor cure kinetics and final properties under processing conditions.
