  • Applications

    sec-Butyl acrylate (CAS 2998-08-5) is primarily used as a reactive monomer in acrylic copolymers, imparting flexibility and a lower glass transition temperature. It is widely used in coatings and inks (including waterborne paints and varnishes), in pressure-sensitive adhesives (PSAs), in sealants, and in UV-curable systems as a reactive diluent, as well as in specialty polymers for textiles, packaging, and plastics to adjust flexibility and processability.
