MEKP Catalyst is a methyl ethyl ketone peroxide in phlegmatiser for the curing of unsaturated polyester resins at ambient temperature in combination with cobalt accelerators.

MEKP Catalyst is a general purpose MEKP and is the workhorse of the Syrgis Performance Initiators line. MEKP Catalyst gives consistent room temperature performance with both resins and gelcoats. A reliable product of remarkable purity, MEKP Catalyst assures quality in almost every system. Suitable applications are: Hand lay-up, spray-up, RTM, continuous laminating, centrifugal casting, filament winding, polyester concrete and vacuum infusion.

A single MEKP initiator formulation cannot provide optimum results in all resin systems. Evaluation of each MEKP in each resin intended for use is absolutely essential before full-scale manufacturing is attempted.
