HexBond® Film Adhesives

HexBond® Film Adhesives designed for demanding aerospace and industrial bonding applications. These adhesives are supplied in film form and rely on elevated temperature curing, typically at 120°C or 180°C under pressure, to achieve their full mechanical properties. This curing process ensures strong, durable bonds that meet stringent structural requirements.

One of the defining characteristics of HexBond® film adhesives is their flexibility in cure cycles. Certain grades, such as HexBond® ST1035, offer broad cure window, e.g. from 10 hours at 90°C up to 45 minutes at 135°C, providing manufacturers with processing versatility. Service temperatures for these adhesives range from −55°C up to 240°C for continuous use, making them suitable for environments where thermal stability is critical.


There are two types of HexBond® film adhesives, HexBond®  312/5 and HexBond® ST1480, each designed for demanding environments and a wide range of substrates.

Answers That Power Precision

Get clarity on your most pressing questions about HexBond® Film Adhesives .

HexBond® 312/5 will be preferred for short cure cycle at 120°C where high shear resistance is required while HexBond® ST1480 will be preferred for higher service temperature applications where toughness and peel performance are key.

Both products are suitable for metal bonding, selection will be made based on the curing process conditions as well as the service temperature of the end-part.

For composite bonding HexBond® ST1480 features outstanding mechanical performance and should be preferred for both composite secondary bonding and co-bonding.

Yes, both products are widely used in aerospace for primary and secondary structures, sandwich assemblies, and more.
