3M Aerospace and Aircraft Maintenance Division 3M™ Scotch-Weld™ Structural Adhesive Film AF 126-2

3M,Ñ¢ Scotch-Weld,Ñ¢ Structural Adhesive Film AF 126-2 is a thermosetting epoxy adhesive film specifically designed for structural bonding applications. It cures at temperatures starting from 180¬8F (82¬8C) and exhibits excellent strength in metal-to-metal, composite, and honeycomb sandwich bonding. The film has low flow during the curing process, which aids in maintaining bond integrity. It is characterized by low tack, facilitating easier handling during application. AF 126-2 is qualified to MIL-A-25463 and MMM-A-132 standards, ensuring its reliability for aerospace and aircraft maintenance applications. The adhesive film requires pressure during curing to maintain alignment and overcome thermal expansion, with recommended pressures ranging from 10 to 25 psi (68.9 to 172.3 kPa). Proper storage conditions include maintaining temperatures at or below 0¬8F (-17.8¬8C) to ensure optimal performance.
