Application
NOROX KP-9 is a general purpose MEKP and is the workhorse of the United
Initiators line. NOROX KP-9 gives consistent room temperature performance
with both resins and gelcoats. A reliable product of remarkable purity, NOROX
KP-9 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 fullscale
manufacturing is?attempted.
