3. Mandatory Companion Materials, Cure Ratios & Hazmat Segregation

DOT 49 CFR & TDG Compliance Policy
Stoichiometric & Catalyst Cure Rule

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.

Required Companion Material Groups for Carbon Fiber Fabrics (3K / 6K / 12K), Spread-Tow & Prepregs:

  • Structural Infusion & Laminating Epoxy Systems
  • High-Temp Nylon Vacuum Film & Release Consumables
  • Structural SAN / Rohacell / Nomex Honeycomb Cores
US DOT 49 CFR § 177.848 & Transport Canada TDG Segregation

Category Profile: Non-Regulated (Subject to US BIS EAR ECCN 1C010 / 1C210). Under federal hazmat regulations, Class 3 Flammable Liquids (UN1866 Resin) and Class 5.2 Organic Peroxides (UN3105 MEKP Initiator) must be packaged in separate UN-certified outer drums/boxes and segregated from Cobalt Octoate promoters to prevent exothermic thermal runaway.
