3M™ Scotch-Weld™ Structural Adhesive Film AF 563 is a high-performance, thermosetting modified epoxy structural adhesive in film form. Scotch-Weld AF 563 film is similar to 3M™ Scotch-Weld™ Structural Adhesive Film AF 163-2 except that Scotch-Weld AF 563 film extends the service temperature range and hot and wet durability of Scotch-Weld AF 163-2 film.

3M™ Scotch-Weld™ Structural Adhesive Film AF 563 is a moderate cure temperature thermosetting structural adhesive film. Scotch-Weld AF 563 is similar to 3M™ Scotch-Weld™ Structural Adhesive Film AF 163-2 except that Scotch-Weld AF 563 extends the service temperature range and hot and wet durability of Scotch-Weld AF 163-2. AF 563 is designed for honeycomb sandwich and solid panel constructions typically found in high performance aircraft structures. It offers high bond strengths from -67° to 300°F (-55° to 149°C), as well as high toughness and peel strength.
Scotch-Weld AF 563 exhibits excellent durability in hot and wet environments and designed for applications where hot and wet service is required. It can be cured as low as low as 250°F (121°C), and can cure with low pressure or vacuum.
The following 3M primers are compatible with AF 563:
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 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.
