AF 32 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 across various environments.
Ultimate Tensile Stress (Scotch-Weld AF 32):
| Temperature (°F) | Temperature (°C) | Ultimate Tensile Stress (psi) | Ultimate Tensile Stress (MPa) |
|---|---|---|---|
| -67°F | -55°C | 9320 psi | 64.2 MPa |
| 75°F | 24°C | 2290 psi | 15.8 MPa |
| 180°F | 82°C | 763 psi | 5.3 MPa |
| 250°F | 121°C | 606 psi | 4.2 MPa |
Structural adhesive films enable the designer to get more innovative with their parts, reducing the overall number of rivets required on structures. 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 to minimize weight while maintaining structural integrity.
The films are available in supported versions, typically used for monolithic bonding or honeycomb sandwich structures. 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.
Adhesive bonding enables a more lightweight structure because it allows more use of lightweight composites instead of traditional metallic materials. Structural adhesive films are employed anywhere metal-to-composite bonding is required. This provides good erosion performance while minimizing weight.
