Abstract (EN): In this work, we study the effect of nanoclay content, aluminum hydroxide and ammonium polyphosphate on the cure of a low-viscosity unsaturated polyester resin, by performing gel-time measurements at 40°C. Results show that, gelation phase decreases with increasing aluminum hydroxide content, ammonium polyphosphate roughly affects gelation and nanoclays have an unexpected effect on gelation. The gelation phase decreases significantly by incorporating 1 wt% of nanoclays, have a slight decrease with 5 wt% and remains roughly unchanged for 10 wt%. The cure rate is faster when nanoclays, ATH and APP are present. For quantities below 10 wt%, the maximum sample attained temperature and nanoclays increase together.
