Features of Nanotect®

Together with Professor Emeritus Inagaki and Professor Emeritus Fukuda from Kyoto University, and GSI Creos Corporation, Takenaka succeeded in jointly developing the world’s first coating with uniformly dispersed high-density CNTs (Carbon NanoTubes), Nanotect®, in 2008. Nanotect® is a dream coating with abrasion resistance, impact resistance, high ductility, high degree of hardness, as well as excellent corrosion resistance properties Takenaka is actively engaged in trialing Nanotect® for applications in areas showing promise, such as medicine, ocean exploration, and aircraft.

Carbon nanotubes have several times the tensile strength of steel and have high conductivity: they are a next generation carbon material. Without being mixed with resin, the conductivity of the carbon nanotube materials cause corrosion, so they were not suitable as a coating for anticorrosion purposes, however, Takenaka’s unique technology called “grafting” successfully blocks the conductivity and disperses the carbon nanotubes uniformly and at high density. The result has been a fusion of the strength of carbon nanotubes with Takenaka’s anticorrosion technology to create the surface treatment, Nanotect®.
