1-Ethylcyclopentyl Methacrylate
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.

1. Flexibilizing comonomer: When copolymerized with harder methacrylates or acrylates, 1-Ethylcyclopentyl Methacrylate contributes flexibility and impact resistance while maintaining outdoor durability, making it useful for architectural and protective coatings. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for 1-Ethylcyclopentyl Methacrylate (CAS 266308-58-1).
2. Adhesion and substrate wetting: The cyclopentyl side group improves wetting on nonpolar substrates and enhances adhesion in adhesive formulations for plastics and composites, contributing to stronger interfacial bonding. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for 1-Ethylcyclopentyl Methacrylate (CAS 266308-58-1).
3. UV-curable systems: It participates in free-radical UV curing to form crosslinked networks with balanced hardness and flexibility, suitable for UV inks, varnishes and coatings where rapid cure is required. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for 1-Ethylcyclopentyl Methacrylate (CAS 266308-58-1).
4. Weathering and chemical resistance: Polymers containing this monomer show improved hydrocarbon and chemical resistance relative to simple alkyl methacrylates, giving longer life in outdoor and industrial applications. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for 1-Ethylcyclopentyl Methacrylate (CAS 266308-58-1).
5. Low volatility and handling advantage: Compared with smaller alkyl methacrylates, its larger side chain reduces volatility, lowering odor and VOC contribution and easing handling in production environments. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for 1-Ethylcyclopentyl Methacrylate (CAS 266308-58-1).
