  • Applications

    2-Butyloctyl 2-methyl-2-propenoate (CAS 10097-26-4) is a long-chain methacrylate ester used primarily as a monomer and reactive diluent in acrylic polymer systems. In practice it is commonly employed as a reactive diluent in UV-curable coatings, inks, and adhesives to impart flexibility and to adjust hydrophobicity while enabling polymerization. It also serves as a monomer for synthesizing flexible acrylic polymers used in coatings for plastics, wood, and metal substrates, and can function as an intermediate in the preparation of specialty polymers with improved weathering and performance. Its long alkyl chain can influence formulation compatibility and rheology, making it a consideration for formulations where enhanced flexibility and low Tg are desired, subject to local regulations and formulation limits.
