Abstract

Abstract This report focuses on epoxy-dicyandiamide (DICY) curing system accelerated by N- aryl-N′, N′-dialkyl urea, aiming at clarifying the accelerating mechanism and the relationship between accelerating effect and molecular structure of the accelerators. Nine N- aryl-N′, N′-dialkyl ureas were synthesized and investigated with measurements of differential scanning calorimetry, thermo gravimetric/differential thermal analysis and NMR ...
