Companion process stack: Marine & Novolac Vinyl Ester Resins (1.25%–2.0% MEKP) + Isophthalic Marine Polyester Resins. Follow HAZMAT SEGREGATION RULE: Organic Peroxides (Class 5.2 UN3105) must be shipped and stored in isolated cabinets away from Cobalt/Amine promoters to prevent self-accelerating decomposition.
Post-Cure Schedule Adjustment Advised: ASTM D648 HDT differs by 29 °C (120 °C vs. 91 °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.
Divergent Hazmat Profiles: Araldite® LY 1564 / Aradur® 22962 is classified as US DOT Class 8 / 9 (Corrosive Polyamine Hardener) (N/A), whereas PRO-SET INF-211 Medium Infusion Epoxy Hardener is classified as Class 8 Corrosive Polyamine (UN2735). Consolidate LTL freight accordingly.
