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.

2. Drop-In & Post-Cure Engineering Verdict

Post-Cure Schedule Adjustment Advised: ASTM D648 HDT differs by 10 °C (85 °C vs. 95 °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.
