Product Introduction
3M™ Scotch-Weld™ Structural Adhesive Film AF 147 is a thermosetting, modified epoxy film adhesive designed for bonding honeycomb structures and metal-to-metal components where high strength at elevated temperatures, up to 300°F (149°C), is required. This adhesive film provides excellent performance across a temperature range from -67°F to 300°F (-55°C to 149°C). Notably, Scotch-Weld™ AF 147 delivers a higher metal-to-metal peel strength compared to 3M™ Scotch-Weld™ Structural Adhesive Film AF 143.
Compatible with specific 3M primers, Scotch-Weld™ Structural Adhesive Film AF 147 ensures optimal bonding performance. The recommended primers for use with AF 147 include:
- 3M™ Scotch-Weld™ Structural Adhesive Primer EC-3917
- 3M™ Scotch-Weld™ Structural Adhesive Primer EW-5000
Ready to Fly: Designed for high-performance aerospace and industrial applications, this structural adhesive film allows for robust bonding of metal and honeycomb materials while reducing reliance on mechanical fasteners like rivets. It enables engineers to design lighter, more efficient structures with fewer rivets, enhancing both durability and performance.
What is Structural Adhesive Film? Structural adhesive films provide an effective solution for reducing the number of rivets needed in aircraft and other high-performance structures. These thermosetting epoxy films are designed for bonding metals, honeycomb cores, and composite substrates. Available in various weights and thicknesses, they allow designers to minimize component weight while maintaining structural integrity.
Structural adhesive films are offered in both supported and unsupported versions. Supported versions are commonly used for monolithic bonding or honeycomb sandwich structures, while unsupported films are ideal for reticulation onto honeycomb. These adhesives cure at temperatures ranging from 180°F to 350°F, providing design flexibility. Unlike paste adhesives, they do not require mixing, making them cleaner and more efficient to use in manufacturing processes.
