Abstract: The reaction proeess of the curing system(epoxy/o-tolylbiguanide)was studied by DSC and carefullyanalyzed. Gel time of the system was tested. Based on the Kissinger and Ozawa equations, the apparent activation energy was calculated 70. 36 kJ/mol and 72.8 KJ/mol, respeetively. The reaction is 0.95 according to Crane theory.

Key words: epoxy powder coatings, reaction order: curing reaction kinetics, o-tolylbiguanide
