Both systems utilize stoichiometric Amine / Polyetheramine Hardeners. Verify exact mix ratio by weight (pbw) on the batch TDS before metering—never substitute hardeners across manufacturers without DSC glass-transition (Tg) qualification.
Post-Cure Schedule Adjustment Advised: ASTM D648 HDT differs by 30 °C (118 °C vs. 88 °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 9 Environmentally Hazardous (UN Number: UN3082). Note 49 CFR § 177.848 segregation if ordering with Class 5.2 Organic Peroxides (UN3105).
