Neopentyl glycol diacrylate with Cas 2223-82-7
What is Neopentyl glycol diacrylate?
The chemical structure of neopentyl glycol diacrylate (NPGDA) consists of two acrylate groups and one neopentyl glycol ester group. The structural characteristic of NPGDA lies in its dual functionality, which contains two acrylate groups that can participate in free radical polymerization reactions and form cross-linked structures. Meanwhile, the neopentyl glycol ester group (derived from 2,2-dimethyl-1,3-propanediol) provides a stable skeletal structure for the molecule.
The appearance of neopentyl glycol diacrylate is a colorless or light yellow transparent oily liquid. It is soluble in organic solvents such as low-carbon alcohols and aromatic hydrocarbons, but insoluble in water. This characteristic enables it to mix well with other organic components during the preparation of coatings, inks, and other processes.
NPGDA, as a bifunctional functional monomer, has good compatibility with acrylic prepolymers and is characterized by strong dilution, good wear resistance, and scratch resistance. It also has high reactivity and can form polymer compounds through free radical polymerization with other monomers or prepolymers.
