High-Performance Materials forComponent Repair
Lufthansa Technik Intercoat, our joint venture with Intercon Holding GmbH (49 percent), specializes in the repair of components, damaged by wear, corrosion, and cavitation, with the "Advanced Epoxy Coating" process. Components which, in the past, would have been scrapped can now be refurbished.
The proven repair procedure called INTERFILL® has been continuously improved over the years INTERFILL® is a material that has been tested for airworthiness and which not only restores the usability of the components, but also leaves them with better operational characteristics than they had in the original state. In order to develop its special characteristics, it is applied like a paste at a thickness ranging from 0.05 to 0.5 millimeters and then cured in a fan-forced kiln. For locally isolated damage, it is possible to fill to a depth of up to 5.0 millimeters. Several variants of the material have been developed, differing in terms of their abrasion resistance, media resistance, and effective operating temperature ranges.
Although INTERFILL® – a mixture of epoxy resin and application-specific filling materials – was initially used exclusively as a high-performance material for engine repair, it now finds almost universal application throughout all parts of an aircraft. The field of application for the "Advanced Epoxy Coating" procedure outside of the aviation industry is also considerable. Already today, many industrial components from the automotive engineering, shipping, gas turbine and machine construction industries are repaired with this high-performance material, opening up new market potential for Lufthansa Technik Intercoat.
