Butanox® M-50A is a versatile methyl ethyl ketone peroxide used for the curing of unsaturated polyester resin at room temperature along with a cobalt accelerator. It can also be used for thermal curing of unsaturated polyester resin under conditions of 100-127 ° C.Butanox ® M-50A has a high content of methyl ethyl ketone peroxide monomer, which provides the resin with a short gel time.
