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 0 °C (105 °C vs. 105 °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 US DOT Class 3 (UN1866 Resin Solution) (UN Number: UN1866). Note 49 CFR § 177.848 segregation if ordering with Class 5.2 Organic Peroxides (UN3105).
