A kinetic model of resol curing in the production of industrial laminates

The kinetics of resol resin cross-linking was investigated by a single-heat ing-rate DSC method. A simple kinetic model was developed, which predicts t he behavior in the industrial impregnation process of laminate manufacture. It was found that the curing rate can be well described by a pseudo first- order kinetic model with apparent activation energy of 87.3 kJ/mol. The kin etic model was verified by comparing calculated and experimental conversion s obtained in the run at the production line.
