  • Applications

    Butanediol dimethacrylate (CAS 2082-81-7) is a difunctional methacrylate monomer used primarily as a crosslinking agent in UV-curable coatings, inks, and adhesives, enabling crosslinked polymer networks with enhanced hardness and chemical resistance. It is incorporated into resin formulations for coatings on wood and plastics, and for encapsulation or protective layers in electronics applications. It may be used as a reactive crosslinker in specialty plastics and composite resins, and may be included in photopolymer systems for 3D printing or other UV-curable technologies.
