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 Nano Tubes), 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.
Rotating Abrasion Test
 Abrasion Resistance |
NANOTECT® has excellent resistance against wear and abrasion. |
|---|---|
| Impact Resistance |
NANOTECT® has the highest impact resistance of all resin coatings. |
| Bending Resistance |
NANOTECT® has very high bending resistance. |
| Film Hardness |
NANOTECT® film is almost as hard as metal coatings. |
| Lubrication |
NANOTECT® has very high lubrication performance like PTFE coating. |
| Anti Corrosion |
NANOTECT® has excellent corrosion resistance with the electric conductivity of CNT insulated by our unique technology of surface grafting. |

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®.  Dispersion effect of Carbon Nanotube on solvent

Examples of application
NANOTECT® is applied to the coated pressure vessel of JAMSTEC’s Otohime (AUV) and a part of Kaikoo (ASV) for anti corrosion.

Metals are known to be subject to extreme corrosion when used in deep sea environments or on long sea voyages.
We are confident that NANOTECT® will protect these materials from corrosion and contribute to the preservation of equipment.
