With composite frames becoming more prominent in the aircraft industry, composite materials for aircraft structures have become more advanced. To preserve the structural integrity of critical aircraft components, manufacturers need adhesives that ensure strong bonds between composite sub-components with excellent chemical resistance and extraordinary mechanical performance. LOCTITE® products for aerospace composite bonding fulfill all these requirements and allow engineers to create strong and efficient aircraft structures.
Needing no fasteners, our adhesives for composite bonding lower adherent thickness that lets you take full advantage of stiffness properties of composites and provides a separation of dissimilar materials.
In the honeycomb and metal assembly segment, Henkel offers metal bonding films for original construction and repair qualified to all major aerospace specifications. LOCTITE® films are one component, heat curing thin film adhesives. These materials are specifically designed for maximum durability, high strength, and toughness with temperature resistance designed for their operating environment.
There are two primary methods for adhesive bond preparation of the surface of a pre-cured carbon fiber composite: Surface abrasion, and the use of release ply fabric, i.e. peel ply. Peel ply is the recommended process because it creates a more uniform surface preparation than hand or machine abrasion.
Henkel’s peel ply makes processes more efficient by minimizing surface preparation. LOCTITE® peel ply provides part longevity and reduces maintenance costs. It ensures a consistent bonding surface with a high-quality bond for today's advanced composite materials.
For high temperatures, wet lay-up, composite construction, or repairs, such as those in aerospace applications, a low viscosity system is needed. This system needs to support both wet lamination processes and out-of-autoclave curing. Henkel offers the perfect solution for the surface preparation of carbon laminates. Our LOCTITE® low viscosity wet lay-up solutions cure very fast under heat and provide an optimal adhering surface for subsequent painting and coating.
Aerospace Potting Compound Benefits:
Potting compounds are available in both one and two component systems from low to medium density as well as in syntactic formulations. Syntactic materials provide structural performance with a lower density by mixing hollow or gas filled micro-balloons into the epoxy base material. These advanced materials are available in both paste and film form, and in expanding and non-expanding formulations.

Ideal for airplane applications, LOCTITE® primers are designed to promote adhesion, protect against corrosion, and improve bond joint long-term durability. They are also available in ozone-safe (non-CFC), solvent-based, and solvent-free formulations.

To reduce weight, honeycomb core structures are used between thin outer wall layers of various substrates, to provide needed rigidity and strength. These honeycomb sandwich panels are used throughout the aircraft, in primary, secondary and interior structures. Where added reinforcement, and particularly compression strength is needed, potting compounds are used to fill the voids within the honeycomb core and to seal the edges.
Strengthening the Core
As the leading global manufacturer of adhesives, Henkel offers a broad range of potting, edge fill and encapsulating compounds for use with a variety of substrates, operating temperatures and other environmental factors. Henkel’s aerospace portfolio provides manufacturers with honeycomb core potting and edge sealing requirements, a range of products that meet critical performance criteria and that are easy to apply and easy to store.

Aerospace Potting Benefits
Potting compounds improve mechanical strength and provide insulation and resistance to vibration and shock. They prevent corrosion from moisture, thermal cycling, dust, and chemicals. Their properties make them well suited for use in aerospace applications.
