Effect of vitrification on the curing reaction of EPY® epoxy system

Polimery 2017, No 5, 394


DOI: dx.doi.org/10.14314/polimery.2017.394

Summary

The curing reaction of the EPY® epoxy system, applied for machine foundation chocks, has been studied at various temperatures. The values of the glass transition temperature (Tg) and the conversion degree (α) in these curing reactions were determined using differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and thermomechanical analysis (TMA). DiBenedetto equation was applied for correlation between Tg and α data. These data showed a one-to-one relationship independent of the curing temperature and good conformableness of DiBenedetto equation with the experimental results at every cure temperature was obtained (Fig. 1). The values of Tg obtained using TMA and DMA methods compared to value obtained by DSC method are 2 and 4 °C higher, respectively.
