Transporting passengers or cargo by rail is already a more sustainable form of mobility than road transport. However, the ambitious task of the collaboration between Lankwitzer, Newag and Covestro was to reduce the use of fossil resources for locomotive coatings even further. Product of choice for the mission was the bio-based hardener Desmodur® eco N 7300.
Sustainable mobility enabled by nature
Lankwitzer’s customer Newag, a leading Polish rail vehicle manufacturer, was driven by the desire to continuously meet customer demands while bringing added value to its customers. Mateusz Fedko, the Newag Project Manager, saw renewable coatings as a key selling point for the company’s diesel locomotives: “A new coating has to fulfill customer specifications, and when it adds value as well, like this bio-based clear coat, this certainly is a great way to differentiate us from our competitors.”
The coating application went as smoothly as the company’s standard clear coat does. Results from tests performed by Lankwitzer and Covestro have demonstrated the clear coat’s excellent performance and proved that it complies with rail industry specifications. Besides a 70% higher scratch resistance and gloss stability compared to standard systems, resistance properties regarding graffiti removal agents are excellent. And Michael Voxbrunner (Lankwitzer) points out: “I’m sure this bio-based clear coat will bring added value to our customers in other industries as well.”
