The First Resin Coating Hybridized with Carbon Nanotube (CNT)


Super-hard, Anticorrosive, CNT-Composited Coating "NANOTECT®"

Super-hard, Anticorrosive, CNT-Composited Coating "NANOTECT®"

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.

ねじアイコンWorld’s first uniformly dispersed carbon nanotubes

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®.
