Neopentyl glycol diacrylate
Neopentyl glycol diacrylate (CAS: 2223-82-7) is a difunctional acrylate monomer with the linear formula (H2C=CHCO2CH2)2C(CH3)2 and a molecular weight of 212.24 g/mol. This compound is characterised by its two reactive acrylate groups, making it a valuable building block in polymer science. It is primarily utilised in applications requiring rapid curing and crosslinking, contributing to the development of advanced materials.

UV-Curable Coatings and Inks
Neopentyl glycol diacrylate serves as a key component in UV-curable formulations for coatings, inks, and adhesives. Its difunctional nature promotes rapid polymerisation upon exposure to UV light, leading to hard, durable, and chemically resistant finishes.
Polymer Synthesis
As a reactive monomer, it is employed in the synthesis of specialty polymers and copolymers. Its incorporation can enhance properties such as hardness, scratch resistance, and adhesion in the resulting polymer networks.
Adhesives and Sealants
The diacrylate functionality facilitates the formation of strong crosslinked networks, making it suitable for use in high-performance adhesives and sealants where robust bonding and environmental resistance are required.
Resin Modification
It can be used to modify existing resin systems, introducing crosslinking sites that improve mechanical properties, thermal stability, and chemical resistance of the final material.
