AF 31 3M Structural Adhesive Film, 20 in x 36 yd (508 mm x 32 m)

3M™ Scotch-Weld™ Structural Adhesive Film AF 31 is a yellow colored adhesive film that provides long-term durability and meets specific challenges for metal-to-metal bonded structures where high temperature performance is desired. Ready to Fly 3M™ Scotch-Weld™ Structural Adhesive Film AF 31 provides excellent performance with easy-to-use shop handling properties. With good peel strength, AF 31 provides reliable, long-term durability and meets the specific challenges of metal-to-metal bonded structures. AF 31 supplies peel strength through a spectrum of environmental conditions and are easy to work with. Once cured it provides high bond strength from -67°F to 500°F (-55°C to 260°C) for use in challenging designs in multiple environments. The films are available in supported versions, which are typically used for monolithic bonding or honeycomb sandwich. 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 required mixing, they offer efficiencies in the design process. They are easier to use than typical paste adhesives.
