In order to limit vibrations and noise pollution, train and tram rails at level crossings are often poured into a rubber-like synthetic resin. This prevents the steel rails from resting directly on the underlying concrete. High demands are placed on this two-component resin, in terms of loadability, flexibility and weather resistance.

Currently, the resin is made from petroleum. In addition, it contains harmful components such as isocyanates. Manufacturer edilon)(sedra however wants to get rid of the hazard labels on its products and asks for biobased materials.

‘That is why in the MAGIC project we are now investigating an alternative based on vegetable oils from Croda’, says project leader Rolf Blaauw of Wageningen Food & Biobased Research. ‘It contains no toxic substances and hardens quickly. With this we have matched the traditional material and created a drop-in. But now we want to go one step further: improving the adhesion to steel and concrete. With the old resins a primer has to be applied now to improve the adhesion. The manufacturer wants to get rid of that, because it would further simplify the processing. That is the challenge we are currently working on, because it is an additional plus point that makes the choice for a biobased resin self-evident. ‘
