Product Introduction
3M™ Scotch-Weld™ Structural Adhesive Film AF 131-2 is a modified epoxy adhesive in film form, engineered to deliver long-term durability and high performance in metal and composite solid panel and honeycomb sandwich construction. It cures at 350°F (175°C) and provides excellent elevated temperature performance, achieving high bond strength at temperatures up to 450°F (232°C). Featuring a glass cloth carrier and a tan color, this adhesive film meets demanding aerospace manufacturing requirements.
Ready to Fly:
3M™ Scotch-Weld™ Structural Adhesive Film AF 131-2 is ideal for bonding honeycomb and metal-to-metal components where high strength at elevated temperatures is required. It performs effectively across a wide temperature range from -67°F (-55°C) to 450°F (232°C). This heat-curing, easy-to-handle film adhesive offers high fracture toughness and peel strength under diverse environmental conditions. Once cured, it delivers durable, high-strength bonds suitable for high-temperature applications in challenging aerospace environments.

What is Structural Adhesive Film?
Structural adhesive films enable innovative designs by reducing the need for mechanical fasteners like rivets, allowing lighter and more aerodynamic structures. These thermosetting modified epoxy films can bond various substrates, including metals, honeycomb cores, and composites. Available in different weights and thicknesses, they help minimize weight while maintaining structural integrity.
These films are offered in supported versions for monolithic bonding or honeycomb sandwich construction and unsupported forms for reticulation onto honeycomb. They cure at temperatures ranging from 180°F to 350°F, offering easier, cleaner processing compared to traditional paste adhesives. With no need for mixing, they enhance efficiency in the design and production process.
3M is on the Leading Edge of Innovation:
Adhesive bonding with structural adhesive films allows for the use of lighter composite materials instead of traditional metals. This approach reduces weight and provides excellent erosion resistance. Structural adhesive films are essential for bonding metals to composites in applications where weight reduction and durability are critical.
