Description

Bisphenol A bis(2-hydroxyethyl ether) diacrylate (CAS No. 64401-02-1) is a high-purity, difunctional acrylate monomer with the molecular formula C₂₅H₂₈O₆. This compound, also known by its IUPAC name 2-[4-[2-[4-(2-prop-2-enoyloxyethoxy)phenyl]propan-2-yl]phenoxy]ethyl prop-2-enoate, is a versatile crosslinking agent designed for advanced polymer applications. Its structure features two reactive acrylate groups linked via a bisphenol A ethoxylate backbone, offering excellent UV curability, adhesion, and chemical resistance. Ideal for coatings, adhesives, and photopolymer formulations, this monomer undergoes rapid polymerization under UV or electron beam irradiation. Supplied as a clear, viscous liquid with low volatility, it is compatible with a wide range of oligomers and resins. Store under inert conditions at recommended temperatures to prevent premature polymerization. Purity: ≥95% (typical), Molecular Weight: 424.49 g/mol.
