EDILON Resin Training resin Theoretical Training EDILON Resin Training Resin Function 1. Fix rail in the groove (guidance system, traffic and dilation forces) 2. Electrical insulation between rail and ground 3. Reduce the gap for pedestrians 4. Auto-cleaning gap 2 EDILON Resin Training Rail preparation • No rust, no oil • Sand blasting of the rail (Sa2 to Sa2,5 - Standard ISO 8501-1) • Only the foot 3 EDILON Resin Training Groove surface preparation Remove the laitance layer (sand blasting, cutting…) 4 EDILON Resin Training Groove concrete strength Adhesive strength of the concrete surface 0.9 MPa 5 EDILON Resin Training Primer U90WB function • Prepare the surface for the resin sticking • Water proof characteristic • Anti rust characteristic • 2 component water based primer 6 EDILON Resin Training Primer U90WB mixing 1 3 2 4 7 EDILON Resin Training Primer U90WB on rail surface • Just after sand blasting U90WB Primer • Bend the rail before put primer • No primer around welding position • 10°C to 35°C / not raining • Curing ti
