Long shelf life, intrinsically flame retardant, transparent, high-performance one-component epoxy resin based on phosphorus-containing imidazole derivatives

High-Performance One-Component Epoxy Adhesive Based on the Synergistic Effect of Lignin-Derived Triaryl-Imidazole and Phytic Acid

“…The problem often leads to structural defects − in the adhesion layer and compromises bonding quality. To address the aforementioned limitations, one-component epoxy resins have been formulated. − The fundamental concept is to impede the electron-rich curing agent at either the phase − or molecular level, − resulting in the latent curing agents. Imidazole derivatives have been extensively researched as intrinsic latent curing agents, and various modification strategies have been devised to incorporate hindered groups, including nucleophilic substitution, ionic complexation, metal coordination, and hydrogen bonding …”
