Neopentyl Glycol Diacrylate with CAS 2223-82-7
What is Neopentyl glycol diacrylate?
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.

Product Advantages
- Fast UV Cure Speed: Bifunctional reactivity enables rapid crosslinking under UV or EB radiation, boosting production line throughput significantly.
- Low Viscosity: Acts as an effective reactive diluent, reducing system viscosity without volatile organic compounds, easing processing and application.
- Excellent Flexibility: The neopentyl backbone imparts outstanding flexibility and impact resistance to cured films — superior to many rigid difunctional alternatives.
- Strong Adhesion: Promotes excellent adhesion to metals, plastics, glass, and wood substrates in both clear and pigmented formulations.
