  • Applications

    Hexyl methacrylate (CAS number: 142-09-6) is used primarily as a monomer for polymers and copolymers, notably poly(hexyl methacrylate), to impart flexibility and chemical resistance. It is also employed in coatings and printing inks as a reactive diluent and monomer for UV-curable systems, helping tune cure speed, hardness, and chemical resistance. In adhesive formulations, it serves as a reactive co-monomer to tailor film-forming properties and adhesion performance. Additionally, as an intermediate in the synthesis of specialty polymers, it enables custom monomer sequences and network architectures in industrial manufacturing.
