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.
Direct Drop-In Qualified: Thermal deflection (ASTM D648 HDT) differs by only 6 °C (82 °C vs. 88 °C). Existing mold cure and demold cycles can be maintained without thermal schedule modification.
Divergent Hazmat Profiles: Henkel Loctite Frekote B-15 Mold Micro-Porosity Sealer is classified as Class 3 Flammable Liquid (UN1263), whereas HK Research MaxGuard NP White Marine ISO/NPG Gelcoat is classified as Class 3 Flammable Liquid (UN1866). Consolidate LTL freight accordingly.
