3M™ Scotch-Weld™ Structural Core Splice Film AF 3028

Highlights:

Variable curing temperature from 250°F (121°C) to 350°F (176°C) helps streamline production

Expands during cure for void filling and core splicing

Low density filler maintains volume against shrinkage

Low sag formula

We developed 3M™ Scotch-Weld™ Structural Core Splice Film AF 3028 as a low density, thermally expanding core splice adhesive film for filling mismatched areas or reinforcing and splicing honeycomb core. With its expansion rate, this core splice film can effectively join honeycomb core of differing cell sizes.

Ready to Fly

We balance 3M™ Scotch Weld™ Structural Core Splice Film AF 3028 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. Its expansion rate allows for successful joining of honeycomb core of differing cell sizes. Please refer to the Tech Data Sheet for specific information.

We formulated 3M™ Scotch Weld™ Structural Core Splice Film AF 3028 to expand during cure for effective void filling and core splicing and will cure nicely through 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 3028 still reaches full expansion. Its low sag properties and low volatile loss during cure, can help provide an excellent solution for mismatched areas or reinforcing and splicing honeycomb core applications. It provides high performance from 67°F to 350°F ( 55°C to 176°C) to ensure a reliable service life.
