1-Ethylcyclopentyl Methacrylate (CAS 266308-58-1) is a methacrylate monomer with formula C11H18O2 and a molecular weight of 182.26 g/mol. It is typically supplied stabilized with small amounts of MEHQ to prevent premature polymerization. This monomer combines the reactivity of the methacrylate double bond with a cyclopentyl-ethyl side group that imparts enhanced hydrophobicity, flexibility and adhesion characteristics to copolymers. It is used in specialty coatings, UV-curable inks, adhesives, and formulations requiring improved outdoor durability and mechanical toughness.
