AKPEROX ER34 is used to cure unsaturated polyester (UP) resins at room and elevated temperatures in the presence of cobalt accelerators. (e.g. AKCOBALT 1% - 6%) The AKPEROX ER34 + cobalt accelerator combination provides faster curing than AKPEROX A50. The setting time of AKPEROX ER34 is usually similar to that of AKPEROX A50. Especially suitable for pipe production and continuous manufacturing applications such as continuous lamination, RTM, centrifugal casting, filament winding, etc.

AKPEROX ER33 is used to cure unsaturated polyester (UP) resins at room and elevated temperatures in the presence of cobalt accelerators. (e.g. AKCOBALT 1% - 6%) The AKPEROX ER33 + cobalt accelerator combination provides faster curing than AKPEROX A50. The setting time of AKPEROX ER33 is faster than both AKPEROX A50 and AKPEROX ER34. It is particularly suitable for pipe production and continuous manufacturing applications with high production rates, such as continuous lamination, RTM, centrifugal casting, filament winding.

AKPEROX ER11 is a phthalate-free mixture of two ketone peroxides (MEKP and AAP) for curing unsaturated polyester resins with cobalt accelerators at room temperature. Compared to cobalt peroxides (MEKP), AKPEROX ER11 with cobalt accelerators provides faster curing speeds and higher peak temperatures at room or elevated temperatures (40-80°C).
