- Norox® MEKP-900 is a general-purpose methyl ethyl ketone peroxide containing high levels of hydrogen peroxide; it serves as the workhorse of United Initiators’ product line. It ensures consistent room-temperature performance with resins and offers exceptional purity.However, a single MEKP initiator formulation cannot provide optimal results in all resin systems; therefore, it is absolutely necessary to evaluate each MEKP in every resin intended for use before proceeding with full-scale production.
