Fast-Curing Flame-Retardant Adhesive

A creamy paste at room temperature, 5 Minute Epoxy FR is flame-retardant, sets fast, and serves as a general-purpose adhesive/encapsulant for potting aerospace inserts and other OEM needs.

It passes the UL 94V-0 burn test and the federal 60-sec vertical burn test (14 CFR 25.853). It fills gaps and bonds rigid substrates such as metals, glass, ceramics, concrete, and wood in all combinations. It comes in cartridges that fit manual or pneumatic applicator guns with static mixing nozzles. It has a viscosity of 115,000 cps, a working time of 3 to 5 min, and a fixture time of 10 to 15 min. It attains functional cure in 2 to 3 hr. VOC emissions are low because the formulation is solvent-free. Cured material typically provides a tensile shear strength of 2,800 psi on cold-rolled steel and dielectric strength of 490 V/mil.
