When used to harden unsaturated polyester (UPR) and vinyl ester resins (VER), high dimer methyl ethyl ketone peroxides (MEKP) alone, or in combination with cumyl hydroperoxide, give longer gel times, do not show a viscosity build up, and do not affect the green strength development as seen in high monomer and/or high hydrogen peroxide MEKPs, or blends of same with cumyl hydroperoxide. These advantages are seen in various resins used for the infusion process, including a VER, two Isophthalic (ISO) resins, one corrosion resistant resin, a high strength ISO resin, and an Orthophthalic resin.
