Companion process stack: Structural Core-Bonding Putty (0.55 kg/m² kerf fill) + Marine Vinyl Ester or Infusion Epoxy Matrix. Follow CORE BEDDING & RESIN UPTAKE: Grid-scored (GS) or grooved/perforated (GP) sheets require ~0.55 kg/m² extra resin for kerf/groove filling or a dedicated structural core-bonding putty.
Post-Cure Schedule Adjustment Advised: ASTM D648 HDT differs by 8 °C (90 °C vs. 98 °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 Non-Regulated (UN Number: N/A). Note 49 CFR § 177.848 segregation if ordering with Class 5.2 Organic Peroxides (UN3105).
