Companion process stack: Marine Vinyl Ester Resin (~0.68 kg/m² per ply in VIP) + Norox MEKP-925H Catalyst (1.5%). Follow RESIN DEMAND FORMULA: 1708 Biaxial (25.5 oz/yd² total) absorbs ~0.95 kg of Vinyl Ester resin per m² per ply in hand layup, or ~0.68 kg/m² per ply under vacuum infusion.
Direct Drop-In Qualified: Thermal deflection (ASTM D648 HDT) differs by only 0 °C (N/A °C vs. 232.2 °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 Non-Regulated Industrial Fiber (UN Number: N/A). Note 49 CFR § 177.848 segregation if ordering with Class 5.2 Organic Peroxides (UN3105).
