1. Catalyst / Hardener Chemistry Comparison

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.

Chomarat Rovicore 600/D3/600 Closed-Mold RTM Flow Glass Companions: Structural Core-Bonding Putty (0.55 kg/m² kerf fill), Marine Vinyl Ester or Infusion Epoxy Matrix, Vectorply 1708 E-Glass / Carbon Skin Plies
Vectorply® E-BXM 1708 Biaxial E-Glass Companions: Marine Vinyl Ester Resin (~0.68 kg/m² per ply in VIP), Norox MEKP-925H Catalyst (1.5%), Divinycell H80 / Corecell M80 Sandwich Core
2. Drop-In & Post-Cure Engineering Verdict

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.
