FM® 400NA is a 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°F/min to 8.5°F/min (1.6°C/min to 4.7°C/min) heat up rate to 350°F (177°C) with a 60 minute hold and 45 psi (0.31 MPa) pressure.

Typical application for FM® 400NA include bonding of honeycomb sandwich structures, as well as metal-to-metal bonding applications.
