Solvay FM® 94U Adhesive Film
Categories: Polymer; Film; Thermoset; Epoxy

Material Notes: Description: FM® 94 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 pre- and post-bond humidity exposure. 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.

Features & Benefits:

  • Demonstrates superior strength in bonding both metallic and composite structures
  • Provides structural performance from -67°F to 220°F (-55°C to 104°C)
  • Offers exceptional elongation and toughness
  • Higher service temperature version of FM® 73 film adhesive
  • Bonding of metallic and composite structures
