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.
Direct Drop-In Qualified: Thermal deflection (ASTM D648 HDT) differs by only 4 °C (88 °C vs. 92 °C). Existing mold cure and demold cycles can be maintained without thermal schedule modification.
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).
