Product Introduction
We developed 3M™ Scotch-Weld™ Structural Core Splice Film AF 3002 as a low-density, thermally expanding core splice adhesive film specifically designed for filling mismatched areas or reinforcing and splicing honeycomb core. With an expansion rate of 35-55%, it is ideal for joining mismatched areas and reinforcing honeycomb core structures.
3M™ Scotch-Weld™ Structural Core Splice Film AF 3002 offers excellent performance along with easy-to-use handling properties, making it suitable for both aerospace manufacturing and MRO. It features variable curing temperatures from 250°F (121°C) to 350°F (176°C), offering flexibility for production processes. Its low-sag formula minimizes rework, while its dry-to-the-touch film form provides cleaner, more efficient application compared to liquid adhesives.
Designed to deliver precise bonding at controlled thickness, this adhesive film ensures strong adhesion, predictable bond lines, and faster assembly. It eliminates the mess and waste associated with liquid adhesives and is suitable for composites, metal-to-metal, and metal-to-honeycomb assembly using heat press or lamination techniques. Key advantages include reduced waste, enhanced efficiency, and precision bonding capabilities, helping to streamline production and reduce costs.
