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.
Direct Drop-In Qualified: Thermal deflection (ASTM D648 HDT) differs by only 2 °C (100 °C vs. 102 °C). Existing mold cure and demold cycles can be maintained without thermal schedule modification.
Divergent Hazmat Profiles: Gurit Corecell M130 Heavy Offshore Hull SAN Core is classified as Non-Regulated Solid Polymer (N/A), whereas Interplastic CoREZYN CORVE8740 Urethane-Modified VE is classified as Class 3 Flammable Liquid (UN1866). Consolidate LTL freight accordingly.
