Details
Highlights
- 250°F (121°C) curing epoxy adhesive film formulated to provide durability in metal and composite bonding of aerospace structures
- Compatible with a range of water-based and solvent-based primers
- Minimum of 50 days out time at 23°C / 75°F without loss in OLS and FRP performance
- Available in a range of adhesive coat weights and supported (carrier) and unsupported constructions for application versatility
- Unsupported version available for reticulation
- Excellent mechanical performance and high peel strength comparable to 3M™ Scotch-Weld™ Structural Adhesive Film AF 163-2
3M™ Scotch-Weld™ Structural Adhesive Film AF 501 is a next-generation 250°F (121°C) curing thermosetting epoxy adhesive film from 3M, building on a heritage of innovation that began with the company’s first epoxy adhesive film for Aerospace applications in the late 1950s. Engineered for the bonding of metal, composite, and honeycomb structures, AF 501 integrates smoothly into established aerospace manufacturing processes, with broad compatibility across surface treatments, water or solvent based primers, and standard cure cycle requirements. For shop-floor efficiency, AF 501 provides a minimum of 50 days out time at 23°C (75°F), giving teams production flexibility.
-
Confidence in every bond3M understands that reliable mechanical performance is critical in aircraft applications, and AF 501 is engineered to meet those demands. It delivers strength and consistency aligned with the flight‑proven, 3M Scotch Weld Structural Adhesive Film AF 163‑2. It maintains high shear and peel strength across a range of temperature conditions, helping ensure durable, long-lasting bonds in critical structural assemblies.
-
Improved overlap shear performanceThis next generation of structural adhesive bonding film takes what worked well on previous 3M products and brings it to another level, including increased shear strength.
