3M™ Scotch-Weld™ Structural Adhesive AF 3185 film is a non-volatile, thermosetting epoxy laminating adhesive and glass cloth combination designed for the structural bonding and for the preparation of reinforced epoxy glass laminate. Scotch-Weld AF 3185 film is commonly used for bonding aircraft canopies and windscreens into frames.
Many 3M adhesive films are designed to bond composite panel or honeycomb sandwich panels for a variety of structural applications
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 the weight while maintaining the 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 required 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 composite, 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.
