FM® 400NA

FM® 400NA adhesive film is the non-asbestos version of FM 400 and is designed to provide similar performance to that of FM 400 adhesive across the board. It is supplied with a lightweight nylon carrier and is designed for bonding metal-to-metal and sandwich composite structures requiring long time exposures to 420°F (216°C). BR® 400 is a modified epoxy corrosion inhibiting primer and provides excellent corrosive resistance when used on aluminum structures. FM 400NA adhesive film will also bond to BR® 127 primer with normal results. Where corrosion resistance is not required, FM 400NA adhesive film can be used without primer. FM 400NA adhesive film can be cured over a wide range of heat-up rates, temperatures and pressures. The recommended cure cycle is a 3 to 8.5°F/min (1.6 to 4.7°C/min) heat-up rate with a 60 minute hold at 350 ± 10°F (177 ± 5.6°C) and 45 ± 10 psi (0.31 ± 0.07 MPa) pressure.
