Henkel Adhesive Technologies, a manufacturer of structural adhesives and surface treatments for the aircraft OEM and MRO industries worldwide, recently developed Loctite EA 9365FST — a two-part epoxy adhesive that reinforces and bonds thermoplastic and thermoset substrates.
Loctite EA 9365FST is available globally and has targeted applications in commercial aviation, defense, and rail applications.
The new formula can serve as a matrix resin on fiberglass to strengthen the thin walls of thermoplastic assemblies. Specifically developed for use in aircraft interiors, the halogen and antimony-free adhesive meets industry fire retardancy, as well as smoke-density and toxicity (FST) requirements.
It’s also REACH and EH&S-compliant worldwide, and is qualified to Boeing’s process specification, BAC 5568.
“Loctite EA 9365FST is a high-tech, FR and FST-qualified technology that has expanded Henkel’s already robust paste adhesive portfolio,” said William Smoot, technical account manager at Henkel Adhesive Technologies. “This product answered a need at Boeing and across the aerospace and rail industries for critical flame retardancy, toxicity, and smoke-suppression adhesives for cabin interiors.”
Loctite EA 9365FST cures in just two hours at 70° C (158° F) or in seven days at room temperature.
Additionally, this user-friendly epoxy provides:
- Excellent mechanical performance when bonding properly treated thermoplastics and thermosets to a range of other substrates
- A balance of adhesion performance and FST compliance
- Good color performance (it does not yellow over time), with less show-through than older adhesive formulations
- The option to use paint
When used as a matrix resin, Loctite EA 9365FST easily wets out fiberglass, strengthening thin thermoplastic assembly walls for enhanced structural support in interior applications, including wall, ceiling and floor panels; compartments and cabin stowage; galleys; lavatories; and seating.
“As product safety and sustainability are increasingly important. This product is sustainable and REACH-compliant with no halogens or other hazardous chemistries,” added Smoot.
