This fire-retardant epoxy fills gaps and bonds well to concrete, wood, glass, fabrics and metals. It is mixed as it is dispensed, with a viscosity of 80,000 cps. It has a working time of 10 minutes, fixes in 20 minutes and cures functionally at 72F in three hours. It has low VOC emissions, is solvent free and its bonds will pass the federal 60-second vertical burn test (14 CFR 25.853/25.885). In cured form, it has a peel strength of 25 pli, resists 10 ft-lbs/in2 impacts, has a dielectric strength of 800 V/mil, and has an adhesive tensile lap shear strength of up to 2,900 psi (as tested on grit-blasted steel at 144F).
