What is Aerospace Adhesive?

Aerospace adhesive is used throughout the interior, exterior and engine compartment of aircraft. On everything from the overhead lockers, to the handy seat trays and even the in-floor lighting. The engine contains threadlockers, retaining compounds, hydraulic system thread sealants as well as structural adhesives. Exterior panels are bonded, wing spars, door moldings … and the list goes on.

Many applications call for the aerospace adhesive according to a specification such as a Mil Spec, ASTM, SAE, or an internal company specification, such as a Boeing specification or a Lockheed Martin specification.

Adhesive selection for other aerospace applications is based on the substrates used and requirements of the bond. So in short, aerospace adhesive is adhesive used in aerospace applications. There is no magic in those adhesives that makes them fly! Many of the adhesives used in aerospace applications are the same products that are used in the automotive industry.

Which are the most common types of aerospace adhesives?

Anaerobics, Structural Acrylics, Epoxies, Cyanoacrylates, as well as adhesive tapes and films are all commonly used as aerospace adhesive.

Anaerobic Adhesives
Are used for threadlocking, retaining, thread sealing and form in place gasketing. Most of these applications are in the engine compartment however threadlockers are used throughout to prevent vibration loosening.

Structural Acrylics
Structural acrylics are used throughout in diverse applications such as bonding magnets into the electric motors and to attach harness clips.

Epoxies
The widespread use of adhesives is driven by the need for strength and weight reduction. The same drivers are spurring the use of carbon fiber within air craft and drones. In addition to Permabond structural acrylics, Permabond ET5428 and ET5429 are ideal for bonding carbon fiber and many other substrates. Lightweight honeycomb edge fillers for bonding composites are often epoxy-based and have a very low density to help keep the plane as light as possible.

Cyanoacrylates
Cyanoacrylates are not only used to permanently bond various items they are also used as a processing aid to instantly hold parts that are being bonded with slower curing adhesives. They are also a quick fix for damaged interior trim (often caused by bored passengers!), taking only seconds to cure, the turnaround time is next-to-nothing.

Although Permabond products are extensively used for their quality and our service, we recognize that in many cases you must start with a specification.
