description Curable resin compositions having extended open times at ambient temperatures and short cure times at elevated temperatures are prepared using a curable resin, a combination of room-temperature-stable liquid peroxides (including at least one perketal), a promoter salt, a thiol-functionalized organic accelerator and a free radical trap. The curable resin compositions are useful in pultrusion, cure-in-place pipe and resin transfer molding applications, among others.
