desired for use with most all resin types. Note: The addition of the red dye
added to this material will aid in mixing and indicate the progression of cure
when color fades away.

Application
NOROX
MEKP-925 FRED is a methyl ethyl ketone peroxide
composition formulated to be an excellent cure initiator for both
unsaturated polyester resins and vinyl ester resins. With most
unsaturated polyesters it gives longer gel and gel to cure times but with
a higher peak exotherm than NOROX
MEKP-9, particularly in thick
sections.
