Our 3M™ Scotch-Weld™ Composite Surfacing Film AF 163-2 encompasses a family of thermosetting modified epoxy adhesives in film form that provides long-term durability and meets specific challenges for metal and composite solid panel and honeycomb sandwich construction, where high fracture toughness and peel strength is required.
Ready to Fly
3M™ Scotch-Weld™ Composite Surfacing Film AF 163-2 provides excellent performance with easy-to-use shop handling properties. This structural adhesive film is available in a variety of weights and carriers to meet a range of needs without imposing excess material costs. With high fracture toughness and peel strength, AF 163-2 provides a reliable, long-term bond suitable for composites, metals in solid panel and honeycomb sandwich fabrication. We also offer an unsupported version, which can be used for reticulation. It is also compatible with multiple substrates and primers. In addition, AF 163-2 exhibits excellent pre-bond humidity performance on composite substrates.
The following 3M primers are compatible with AF 163-2:
Our heat-curing, easy handling film is designed to meet numerous customer specs in aerospace manufacturing. AF 163-2 supplies high fracture toughness and 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 250°F (-55°C to 121°C) for use in multiple designs through multiple environments.
