Polyethylene Glycol 400 Diacrylate (PEG400DA) – Difunctional Acrylate Monomer for Advanced UV-Curable Systems

Polyethylene Glycol 400 Diacrylate (PEG400DA) is a difunctional acrylate monomer consisting of a polyethylene glycol (PEG) backbone with an average molecular weight of 400, terminated by two highly reactive acrylate groups. This structure makes PEG400DA an excellent crosslinking agent for the development of high-performance polymers and resins.

PEG400DA is widely used in UV-curable coatings, adhesives, inks, sealants, and 3D printing resins, where it imparts flexibility, toughness, chemical resistance, and low shrinkage during curing. Its hydrophilic PEG backbone enhances compatibility and processability, while the diacrylate functionality ensures strong and durable crosslinked networks.

In applications such as optical materials, biomedical devices, and additive manufacturing, PEG400DA contributes to improved dimensional stability, impact resistance, and weatherability. It is especially valuable in energy-curable systems (UV or electron beam curing) that demand fast polymerization, low odor, and high-performance properties.

With its balance of reactivity, flexibility, and durability, Polyethylene Glycol 400 Diacrylate (PEG400DA) is an essential raw material for next-generation coatings, adhesives, and 3D printing formulations.
