With a length of more than 10 km, Niyayesh Tunnel was inaugurated on February 16, 2013.
In an interview with Iran Nanotechnology Initiative Council's reporter, CEO of Pishgaman Fanavari Asia Company Sajjad Dibayee Asl stated that the experience of the Municipality of Tehran in using traffic nanopaints in various projects and the advantages of nanopaints over other types of paints were the main reasons for the application of such nanopaints in Niyayesh Tunnel.
According to Dibayee Asl, over 5 tons of nanopaints have been used in the painting of the northern lanes in Niyayesh Tunnel due to their high resistance against chemical pollutants and also due to their desirable light reflection.
In comparison to ordinary paints, single and double part cold traffic nanopaints made by this company have higher lifetime, and they have applications in painting civil traffic lines, pedestrian lines, warning lines, and street blocks. The municipalities of Orumiyeh, Torbat Heidariyeh, Tehran, and Mahshahr Port have so far used these nanopaints in their projects.
