Investigating the Solubility of 2-Ethyl-4-Methylimidazole in Various Epoxy Resins Abstract: 2-Ethyl-4-methylimidazole (2E4MI) is a widely used curing agent and accelerator in epoxy resin systems due to its ability to initiate polymerization at relatively low temperatures and its favorable impact on the mechanical and thermal properties of the cured resin. Understanding its solubility in different epoxy...
