3M™ Scotch-Weld™ Structural Core Splice Film AF 3002 is developed as a low density, thermally expanding core splice adhesive film designed for filling mismatched areas or reinforcing and splicing honeycomb core. With its 35-55% expansion rate, it is ideal for filling mismatched areas, and for splicing and reinforcing honeycomb core.
The 3M™ Scotch-Weld™ Structural Core Splice Film AF 3002 has balanced properties to provide excellent performance with easy-to-use shop handling characteristics. This heat-curing, easy handling film is designed to meet numerous customer specs in aerospace manufacturing and MRO. Its expansion (35 – 55%) allows for the successful joining of mismatched honeycomb structures, and its low sag during cure helps eliminate the need for rework.
