Model-fitting and model-free nonisothermal curing kinetics of epoxy resin with a low-volatile five-armed starlike aliphatic polyamine

► Nonisothermal cure reaction of DGEBA/PADT is examined with DSC. ► Model-fitting and advanced model-free isoconversional methods are used to the curing kinetic analysis. ► Reaction rate equation is established with the Málek method. ► Effective activation energy determined from the Vyazovkin method is interpreted in detail. ► Isothermal conversion prediction from the nonisothermal data is accomplished.
