What is ITRO Technology?

ITRO® surface treatment (Japanese Patent No. 3557194)- our innovative Nanocoat technology enables the surface of the substrate instantaneously hydrophilized by a combustion of chemical vapor deposition phase

The method involves spraying a gas containing a silicon compound to the surface while burning it.

Generating nanocoating structure on the substrate


The result- a nano-order silicon oxide coating layer on the surface, with fine particles of silicon oxide generated by the combustion’s.


Electron micrograph : Before and after ITRO treatment show Generating nano order silicon oxide (SiO2) coating layer on the PP surface. It shows better than traditional surface treatment technologies.
