In this study, we attempt to explain the cure kinetics of DGEBA/MDA/NPG system as a function of the concentration of the NPG. Regardless of the NPG content, the shape of the conversion curve showed sigmoid, and this meant that DGEBA/MDA/HPG system followed autocatalytic cure reaction. The cure reaction of DGEBA/MDA/NPG system increased with the increment of NPG content. This is due to the catalytic role of two hydroxyl groups in NPG and the generated hydroxyl groups of DGEBA/MDA system.
