Answers That Power Precision

Get clarity on your most pressing questions about HexBond® Foaming Adhesive Films.

HexBond® Foaming Adhesive Films are expandable adhesives designed to fill gaps and bond irregular surfaces during the curing process. They are widely used in aerospace and industrial applications for honeycomb splicing and sandwich structures, offering lightweight construction, strong adhesion, and thermal stability.

Their expandable formulation reduces the need for additional fillers and simplifies assembly, saving time and minimizing material waste.

These adhesives bond effectively to metals, composites, and honeycomb cores, making them versatile for aerospace and industrial structures.

Yes, both the 200 Series and ST1150 should be stored at or below −18°C to maintain shelf life and performance.

Yes, their gap-filling capability and strong adhesion make them suitable for structural repairs and core splicing in service environments.

The 200 Series offers a range of expansion ratios for honeycomb splicing and gap filling, while ST1150 is a dual-cure core splice adhesive qualified, with specific expansion performance at different cure temperatures.

Yes, both products are widely used in aerospace for lightweight structural bonding, especially in sandwich and honeycomb assemblies.

Both products cure at standard aerospace temperatures (120°C or 180°C),but always refer to the technical data sheet for specific recommendations.

Always follow Hexcel’s recommended handling procedures, including proper PPE and curing protocols, as outlined in the technical data sheets.
