Henkel (Toulouse, France and Bay Point, Calif.) displayed its LOCTITE EA 9845 EC lightweight surfacing film with incorporated expanded copper foil lightning strike protection (LSP), which reportedly offers a 30 percent weight reduction compared to other LSP products. The epoxy-based system cures at 120°C to 176°C (248°F to 349°F) and reportedly reduces surface imperfections and prepaint surface preparation while boosting UV and chemical resistance. On-stand at JEC, Henkel displayed a Learjet 85 tailcone section manufactured by Bombardier in Querétaro, Mexico, which has qualified the new lightweight LSP for use across the aircraft’s fuselage.
