A white/off white powder curative used as a polymerization initiator for plastics and resins. It is added in quantities of .5 to 5% to cure resins such as styrenes, polyesters (including thermoset resins), vinyl acetate, acrylonitrile, acryl esters, diallyl phthalate and other similar resins and/or combinations thereof. It is also used as an alternative for the more hazardous methyl ethyl ketone peroxide (MEKP). Heat and/or Perkadox 14S-FL (listed below) is applied to increase the (cure) rate of polymerization. Powder replacement for the more hazardous, hard to get Methyl Ethyl Ketone Peroxide.
