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.
Direct Drop-In Qualified: Thermal deflection (ASTM D648 HDT) differs by only 0 °C (91 °C vs. N/A °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 8 Corrosive Polyamine (UN Number: UN2735). Note 49 CFR § 177.848 segregation if ordering with Class 5.2 Organic Peroxides (UN3105).
