Product name: Neopentyl glycol diacrylate
English alias: NPGDA; 2,2-Dimethyl-1,3-propanediol diacrylate.
CAS: 2223-82-7
Molecular formula: C11H16O4
Appearance: Clear liquid
Package: 25kg/drum
Neopentyl glycol diacrylate is a difunctional acrylic monomer characterized by its low viscosity and excellent reactivity. This monomer features two acrylate functional groups attached to a neopentyl structure, which provides exceptional hardness, chemical resistance, and weatherability to cured products. NPGDA is widely used as a crosslinking agent and reactive diluent in UV/EB curing systems. Its balanced properties of fast cure speed, low volatility, and good dilution capability make it an essential component in various radiation-curable formulations.
