Companion process stack: Low-Viscosity Infusion Epoxy (Gurit Prime 37 / Hexion RIMR 135 / Araldite LY 1564) + Stoichiometric Amine Hardener. Follow SIZE COMPATIBILITY: Use Epoxy-compatible silane sizing with Structural Epoxy Resins (approx. 55:45 fiber-to-resin weight ratio in vacuum infusion). ITAR/EAR export screening applies.
Direct Drop-In Qualified: Thermal deflection (ASTM D648 HDT) differs by only 0 °C (N/A °C vs. 260 °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 Non-Regulated Industrial Fiber (UN Number: N/A). Note 49 CFR § 177.848 segregation if ordering with Class 5.2 Organic Peroxides (UN3105).
