Companion process stack: Butyl Vacuum Sealant Tape (GS-213-3) + Perforated Release Film & Peel Ply. Follow COMPLETE INFUSION STACK: Laminate → Peel Ply (85 gsm Nylon) → Perforated Release Film → HDPE Spiral Flow Media → Spiral Tubing & Omega Channels → Butyl Tacky Tape → Nylon Vacuum Film.
Post-Cure Schedule Adjustment Advised: ASTM D648 HDT differs by 79.4 °C (125 °C vs. 204.4 °C). For elevated-temperature tooling or dark-colored marine hulls, perform a 4–6 hour post-cure ramp at 60–80 °C (140–176 °F) to lock in full cross-link density.
Identical Hazmat Logistics Profile: Both SKUs ship under US DOT 49 CFR & Transport Canada TDG as Non-Regulated Industrial Consumable (UN Number: N/A). Note 49 CFR § 177.848 segregation if ordering with Class 5.2 Organic Peroxides (UN3105).
