Both matrices cross-link via free-radical polymerization using 1.25%–2.0% MEKP (Methyl Ethyl Ketone Peroxide, UN3105) or Cumene Hydroperoxide (CHP) with Cobalt Octoate promoter. Low-hydrogen-peroxide MEKP (e.g., Norox MEKP-925H) is recommended to eliminate micro-foaming.
Post-Cure Schedule Adjustment Advised: ASTM D648 HDT differs by 41 °C (105 °C vs. 146 °C). For elevated-temperature tooling or dark-colored marine hulls, perform a 4–6 hour post-cure ramp at 60–80 °C (140–176 °F) to lock in full cross-link density.
Identical Hazmat Logistics Profile: Both SKUs ship under US DOT 49 CFR & Transport Canada TDG as Class 3 Flammable Liquid (UN Number: UN1866). Note 49 CFR § 177.848 segregation if ordering with Class 5.2 Organic Peroxides (UN3105).
