FM 94 film adhesive is a 220°F/104°C service temperature, modified epoxy film adhesive designed for bonding metallic and composite structures. FM 94 adhesive offers a unique combination of high temperature performance, toughness and moisture resistance as demonstrated by its ability to bond to wet Nomex* honeycomb and retention of shear properties after prebond and postbond humidity exposures. FM 94 adhesive is designed for applications demanding the best of both 220°F/104°C service temperature and -67°F/-55°C peel strength.

For composite and metal bonding applications, FM 94 adhesive is formulated to exhibit superior elongation, toughness and shear strength properties. The controlled flow characteristics allow for its use in co-cured applications as well as bonding pre-cured structures. Also, FM 94 adhesive provides excellent electrical insulation between metal and graphite composites, reducing the potential for galvanic corrosion.

FM 94 film adhesive is manufactured as a supported adhesive with both knit and mat carriers, or as an unsupported film. When supported with a knit carrier, optimal mechanical properties can be obtained. The random mat provides superior handling characteristics. With the mat carrier, FM 94 adhesive can be supplied in a one-side tacky (OST) version which helps reduce air entrapment when bonding large metal or composite parts.
