ALKYD-BASED-THERMOSETTING RESIN - CALORIMETRIC INVESTIGATIONS OF THE CURING PROCESS

In this work, the rate of cure of different oxidative drying oil modif ied alkyd resins are investigated by DSC measurements. We determine, f rom the Kissinger equation, the apparent activation energy of the curi ng process. We show that this activation energy depends on the curing duration and that these variations lead to the determination of a time constant, characteristic of the material.
