3M™ Scotch-Weld™ Structural Core Splice Film AF 3024

• Variable curing temperature from 250°F (121°C) to 350°F (176°C) helps streamline production
• 250% expansion rate allows for successful joining of greatly mismatched honeycomb structures
• Qualified to multiple aerospace customer specs
• Versatile performance and application allows for consolidation and standardization of inventory
• Low sag formula helps eliminate rework

We developed 3M™ Scotch-Weld™ Structural Core Splice Film AF 3024 as a low density, thermally expanding core splice adhesive film designed for filling mismatched areas or reinforcing and splicing honeycomb core. With its 250% expansion rate this core splice film can effectively join significantly mismatched honeycomb structures.

Within the 3M core splice film product family, Scotch-Weld™ AF 3024 has the highest expansion

Ready to Fly
We balance 3M™ Scotch-Weld™ Structural Core Splice Film AF 3024 properties to provide excellent performance with easy-to-use shop handling characteristics. Our heat-curing, easy handling film is designed to meet numerous customer specs in aerospace manufacturing and MRO. Its high expansion (250%) allows for successful joining of significantly mismatched honeycomb structures and its low sag during cure helps eliminate the need for rework.

3M™ Scotch-Weld™ Structural Core Splice Film AF 3024 will cure at a range of temperatures from 250°F (121°C) to 350°F (176°C). This variable cure rate combined with the film's easy handling gives you flexibility to design efficient processes. Even at slow heat up rates as low as .5°F/minute, AF 3024 still reaches full expansion.
