Product Introduction
3M™ Scotch-Weld™ Structural Adhesive Film AF 143-2 is a high-performance, heat-curing adhesive film engineered for structural bonding in demanding aerospace applications. It excels at joining honeycomb and metal-to-metal components, delivering exceptionally high bond strength at elevated temperatures up to 350°F (177°C). This adhesive maintains its robust performance across a wide operational temperature range from -67°F to 350°F (-55°C to 177°C), providing high fracture toughness and peel strength in various environmental conditions. Designed for easy handling in shop environments, it features an embossed liner and is compatible with 3M™ Scotch-Weld™ Structural Adhesive Primer EC-3917. AF 143-2 enables lighter aircraft designs by reducing the need for mechanical fasteners in both solid panel and honeycomb sandwich structures.
3M™ AF 143-2 Features:
- Designed for a 350°F (177°C) cure cycle.
- Provides high bond strength for honeycomb and metal-to-metal components at 350°F (177°C).
- Maintains excellent performance across a -67°F to 350°F (-55°C to 177°C) temperature range.
- Offers high fracture toughness and peel strength.
- Includes an embossed liner for easy application and handling.
- Tan in color for visual identification.
3M™ AF 143-2 Applications:
- Bonding of honeycomb and metal-to-metal components requiring high strength at elevated temperatures.
- Fabrication of composite and metal solid panels.
- Construction of honeycomb sandwich structures.
- Aerospace designs where high fracture toughness, peel strength, and lightweighting are critical.
- Applications requiring efficient, clean processing compared to paste adhesives.
