Kinetics of the curing process of alkyd-melamine resin systems
The aim of this work was to investigate the nature of the curing process of an alkyd-melamine resin mixture, and to determine the kinetic parameters from DSC measurements (Perkin-Euner 2). The experiments were performed using both the dynamic method, with variation of peak exotherm temperature with...

description | The aim of this work was to investigate the nature of the curing process of an alkyd-melamine resin mixture, and to determine the kinetic parameters from DSC measurements (Perkin-Euner 2). The experiments were performed using both the dynamic method, with variation of peak exotherm temperature with heating rate, and the isothermal method. A single broad peak was observed in all experiments. Practically no reaction was observed below 350 K. From the dynamic experiments at four heating rates an activation energy of 78.7 kJ mol
−1 was obtained. More precise results were obtained from isothermal experiments by scanning the temperature range 415–430 K: a reaction order very close to one, reaction rate constants from 0.76 to 0.85 s
−1 and an activation energy of 60.2. |
