Neopentyl Glycol Diacrylate (NPGDA) is a bifunctional acrylate monomer derived from neopentyl glycol and acrylic acid. Its two reactive acrylic double bonds allow it to rapidly polymerize under UV or electron-beam (EB) irradiation, forming tightly crosslinked polymer networks. NPGDA is valued for its combination of low viscosity, fast reactivity, and the unique flexibility imparted by the neopentyl backbone — avoiding the brittleness associated with many other difunctional monomers. In UV/EB curable systems, NPGDA serves a dual role: as a reactive diluent to reduce formulation viscosity without adding VOCs, and as a crosslinking agent that improves hardness, chemical resistance, and coating integrity.
