Lord Corp., a supplier of motion control and adhesive technology, has introduced UltraConductive Film and Coatings for lightning-strike protection.
The manufacturer says the aircraft coatings offer the same degree of lightning-strike protection as conventional expanded metal foils at half the weight.
The non-nano epoxy resin, with a proprietary conductive filler, can be co-cured with composite aircraft structure as an in-mold surfacing film or as a spray coating, replacing traditional expanded metal meshes and foils, the company says.

| The coating offers a comparable degree of protection as metal foils, but at half the weight, the manufacturer says. |
Lord says the product offers a 55 percent direct weight savings over copper and reduces the amount of primer and paint needed to achieve a smooth part surface.
UltraConductive can be readily repaired, is not affected by salt corrosion or sun exposure, and does not negatively impact part mechanical properties, according to the manufacturer.
Protection, Savings Cited
“Lord UltraConductive Film and Coatings protect composites at half the weight and enable OEMs to improve throughput,” said Seth Carruthers, Ph.D., Lead Staff Engineer, Chemical Engineering. “OEM evaluations are uncovering savings in part fabrication costs and long-term cost of ownership compared to the conventional use of expanded metal foil.”
