What is Poly(ethylene glycol) diacrylate CAS 26570-48-9?
Poly(ethylene glycol) diacrylate (PEGDA) CAS 26570-48-9 is a homobifunctional PEG derivative capped with reactive acrylate groups at both ends. It serves as a highly versatile crosslinker, prepolymer, and UV‑curable monomer, widely used for hydrogel synthesis, 3D printing resins, biomedical materials, coatings, and advanced polymer networks.
