Flame-Retardant Structural Epoxy

It's flexible, resists impacts, and can secure honeycombed floor and ceiling panels in airliners. Mixed as dispensed, the epoxy has a 80,000-cps viscosity, a 10-min working time, and fixes in 20 min with a 3-hr functional cure at 72°F. Bonds pass the federal 60-sec vertical burn test (14 CFR 25.853/25.885) with low VOC emission. Once cured, the epoxy provides a typical peel strength of 25 pli, impact resistance of 10 ft-lb/in.2, dielectric strength of 800 V/mil, and adhesive tensile lap shear strength of up to 2.9 kpsi (as tested on grit-blasted steel at 144°F).
