  • Applications

    Methyl 2-allyl acrylate (CAS 51122-89-5) is used primarily as a reactive monomer in coatings, inks, and adhesive formulations, enabling rapid radical polymerization to form acrylate networks. The allyl functionality allows controlled crosslinking and network formation, which makes it suitable for UV-curable coatings and UV-curable inks; high-performance adhesives and sealants; specialty polymer resins for electronics encapsulation or protective conformal coatings; polymer binders for plastics and textiles; and as a reactive diluent or crosslinking agent in composite formulations.
