AF 30 supplies peel strength through a spectrum of environmental conditions and is easy to work with. Once cured, it provides high bond strength from -67°F to 350°F (-55°C to 175°C) for use in challenging designs in multiple environments.
What is Structural Adhesive Film?
The fewer rivets you have in your aircraft, the better. Structural adhesive films enable the designer to get more innovative with their parts and reduce the overall number of rivets required on your structure. This thermosetting modified epoxy in film form can be used for bonding a wide variety of substrates, including metal, honeycomb, and composite. Structural Adhesive Films come in a variety of weights and thicknesses, minimizing weight while maintaining structural integrity.
The films are available in supported versions, which are typically used for monolithic bonding or honeycomb sandwich. They are also available in unsupported form for reticulation onto honeycomb. These films can be cured from temperatures as low as 180°F to as high as 350°F. Because these films are less messy and don’t require mixing, they offer efficiencies in the design process. They are easier to use than typical paste adhesives.

3M is on the Leading Edge of Innovation
Adhesive bonding enables a more lightweight structure because it allows you to use more lightweight composites, as opposed to the metallic materials that were used in previous designs. Structural adhesive films are employed anywhere you are trying to bond metal to composite. This offers good erosion performance while minimizing weight.
