Application
Norox MEKP-9H is an excellent liquid general-purpose cure initiator for the
room temperature cure of polyester resins. In this application it imparts medium
to high exotherm characteristics to the cure. Norox MEKP-9H gives excellent
performance as a curing agent for gel coats. Resin suppliers should be
consulted for specific recommendations for individual resins. Norox MEKP-9H
is highly refined and substantially free of water, hydrogen peroxide and methyl
ethyl ketone. Compared to Norox MEKP-9, with most polyester resins Norox
MEKP-9H gives a slightly longer gel time with a similar total cure time.
