(ATO・TO・PTO)Transparent Conductive Materials
Our Transparent Conductive Materials (TCM) consist of spherical primary particles with diameters shorter than the wavelength of visible ray. When a coating agent is made with an uniform dispersion of TCM, a transparent substrate can be attained with an anti-electrostatic performance. Made with tin oxide as a basic ingredient, TCM offers high performance against heat, chemicals, and severe weather.

Our unique technology made it possible to create Transparent Dispersion Liquid (TDL) from TCM which are dispersed uniformly in water without dispersant additives. With a water-based binder, TDL can be mixed easily, allowing easy production of water-based paints that provide high transparency and anti-electrostatic performance.
