Rebuilt by Newag from a TEM2 diesel locomotive, ENEA 15D-031 awaits an entry into service at the Newag works in Nowy Sącz. Together with 15D-032, it received a paint based on renewable resources, supplied by Lankwitzer Lackfabrik of Berlin and developed in collaboration with Covestro. Picture by Covestro.
In the second half of 2016, Newag delivered two 15D diesel locomotives to ENEA S.A., rebuilt from old TEM2 diesels: 15D-031 and 15D-032. The two locos have been coated with a paint based on renewable resources. Lankwitzer Lackfabrik of Berlin supplied the coating, which it developed in close collaboration with Covestro using the biobased coating hardener Desmodur Eco N 7300. Mateusz Fedko, project manager at Newag, states: “If the coating offers added value on top of that, as is the case here with the renewable raw materials, it gives us a very good opportunity to set ourselves apart from the competition".
According to Covestro, the coating formulated with this product performs just as well as a conventional coating systems, but uses primarily renewable resources. “Seventy percent of the carbon in this polyurethane raw material comes from biomass”, says Julia Hellenbach of Covestro. The biobased clearcoat fulfills the specific demands of the rail vehicle industry. For example, it has a very good resistance to cleaning agents, particularly those used to remove graffiti. Tests confirm that graffiti can be removed easily and gently.
