  • Applications

    Docosyl methacrylate (2-Propenoic acid, 2-methyl-, docosyl ester; CAS 16669-27-5) is primarily used as a specialty monomer for long-chain alkyl methacrylate polymers and copolymers. In industrial applications, it is used in coatings, inks, and UV-curable formulations to impart hydrophobicity, flexibility, and gloss to resin films, and it can function as a reactive diluent or co-monomer to tailor processing and final properties in adhesives and specialty plastics. Accordingly, it is commonly evaluated for use in polymer and coating formulations where the long alkyl side chain enhances surface properties and performance, subject to processing requirements and regulatory constraints.
