For tetrafunctional formulations, Florys classic analysis yields the value of 58% for conversion at gel point. This study utilizes a recently developed mechanistic kinetic model for epoxy-amine reactions to calculate the time needed to reach 58% conversion. That time was then compared to the gel time determined from rheological measurements and the two were found to be in superb agreement
