* Gel time and reactivity will vary due to the type and concentration of Free Radical Initiator (catalyst), shop temperature, humidity, and type of fillers used. In order to meet
your individual needs consult our technical sales representative for assistance. If using methyl ethyl ketone peroxide (MEKP) to gel and cure CoRezyn vinyl ester
resins, we recommend only these three brands: Cadox L-50a (Akzo Nobel); Luperox DHD-9 (Arkema); and Norox MEKP-925 (United Initiators). These must be
used at the appropriate percentage and suitable temperature. Contact your Interplastic Corporation representative for assistance.
