Making Aircraft
Interiors Lighter,
Stronger, and
Quieter

Specially developed for aerospace and aircraft cabin interior applications, our clean, safe, and efficient solutions enable the high-performance bonding, filling, and joining of metal, honeycomb core, thermoplastics, and composites, as well as fast and efficient splice bonding and edge finishing.

All aerospace solutions comply with the latest FAA and EASA FST regulations, including FAR 25.853, ABD0031, FAR/JAR 25.853 (vertical burn, smoke density and toxicity), to simplify parts certification and for passenger safety.

FST Bonding Solutions for Aircraft Interiors

These two-component toughened adhesives cure at room temperature and provide high-performance bonding. Designed for interior applications, they meet the latest FAA fire regulations: vertical burn, smoke density, and toxicity.

The adhesives are available in two different open time versions for immediate bonding (12 to 20 min.) and long (90 to 120 min.) for larger parts.

FST Foaming Adhesives

Depending on which formulation is chosen and the cure cycle used, expansion rates can range from 30% to 400%. Some of L&L’s products are Airbus-qualified.

They are available in both sheet form and as extruded beads. The tacky nature of L&L core splice adhesives means that no additional adhesive is required to pre-bond to the honeycomb.

Honeycomb Panel Reinforcements

Mixing or weighing of separate components is not required. The panel reinforcement material is available as a high-viscosity paste for manual application and in a low-viscosity state for use with a mechanical pump. Once cured, it can be readily machined and sanded.

A New Approach to Fill and Reinforce
Aerospace Sandwich Panels: L-9060

By working closely with aerospace customers, L&L Products discovered a need in the industry for a solution that would locally reinforce honeycomb panel structures or close-out panels to protect against impact or humidity. In order to address this need, L&L Products developed L-9060, an epoxy-based syntactic FST aircraft interior edge and core filler compound. L-9060 not only successfully locally reinforces honeycomb panel structures, it also solves issues caused by the manual process of alternative solutions.
