3,4-Epoxycyclohexylmethyl 3,4-Epoxycyclohexanecarboxylate
3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexane carboxylate (ERL-4221) CAS 2386-87-0 is a difunctional cycloaliphatic epoxy monomer widely used in high-performance thermoset formulations. The molecule contains two 3,4-epoxycyclohexyl moieties linked via an ester bridge, delivering low-viscosity, highly reactive epoxy functionality with excellent UV and thermal stability. ERL-4221 is favored for coatings, laminates, adhesives and composite matrices where weathering resistance, low yellowing and good electrical insulating properties are required. Its cycloaliphatic epoxy structure yields cured networks with improved toughness and hydrolytic stability compared to aromatic epoxies.
