Modeling and experimental verification of the curing kinetics of an Epoxy/Polyaminoamide/Nano-glassflake systemby DSC

Requirements of improved corrosion resistivity and mechanical properties of the epoxy coatings lead to the use of composite systems with the addition of glass flake in the epoxy coatings[۱]. Curing is a determining step in coating process and properties as well. So, the understanding of the mechanism and kinetics of cure is the first essential step in the evaluation of processing-property relationship [۲]. In this work, the curing kinetics of diglycidyl ether of bisphenol-A epoxy resin cured with a polyaminoamide in the absence and presence of nano-glassflakes (NGF) were studied by means of non-isothermal differential scanning calorimetry (DSC) experiments at four heating rates.
