TECHNICAL INFORMATION

Visible Light Response Type Photocatalytic Materials(Silver Nano Colloides, Hydroxy Apatite complex type)
FUJI SP TiO2, WO3 series
FUJI ASL TiO2, WO3 series
We have developed FUJI SP, ASL TiO2, WO3 series as Visible Light ResponseType Photocatalytic Materials based on years of our experience in the field oforganic pigment, functional material manufacturing technology, industrial powder
fine grinding, nano size particle dispersion technique.

We had modified thesurface and bulk property of TiO2 and WO3 to possess visible light response.
Moreover, by making complex with silver nano colloids and hydroxyl apatite,
they can absorb (night time, in the dark) and decompose bacteria (day time,under illumination). This is very original to our company technology.

Belowfigure indicates the photo degradation rate property of methylene blue with our
photocatalytic materials.

TECHNICAL INFORMATION

Particle Diameter Distribution
Based on our fine particle dispersion technique, we can control the size of nanoparticle diameter, such as to make particle size smaller in order to increase theavailable chemical reaction site, in order to obtain more photocatalytic sites atsurface. Please consult us anytime to modify particle size diameter including
surface properties.

We are also developing printable ink or paint for Photocatalytic paint using FUJI
TiO2 or WO3 series based on water, or any type of organic solvent.
For example, below table indicates the basic property of paint or ink slurry.
FUJI ASL TiO2 or WO3

10.0 – 40.0 %Resin and additive

0.8 – 12.0 %Silver Nano Colloids

0.01 - 5.0 %Hydroxy Apatite

0.01 - 10.0 %Water or Organic Solvent (Terpineol,NMP, MIBK, Toluene, BCA etc…)

50.0 - 80.0 %4.0 – 300000 mPa・s/ 25 °C

Viscosity(Viscosity can be modified for customer’s request
for their printing method)

Particle size of FUJI ASL TiO2 or WO3

60.0 nm – 300.0 nm

TECHNICAL INFORMATION

We can prepare ink or paint slurry either organic solvent base such as IPA (isopropyl alcohol), MEK (n-methyl pyrrolidone), NMP (N- Methyl pyrrolidone)
etc…..and water. We can also modify the particle size, concentration of otheradditives such resin or dispersing chemical etc… We will prepare suitable ink
using appropriate resin and chemicals in order to have strong adhesion towards
substrate such as PET, PP, PE film, glass, metal, or ceramic substrate, as
customer requests.

Furthermore, we can perform surface coating, metal

doping, inorganic oxide coating (SiO2, Al2O3, ZrO2 etc…) and so on, in order tomodify particle property. (To prevent substrate damage caused by TiO2 or WO3
photocatalytic property itself).

In addition, we can also modify the amount ofsilver nano colloids and hydroxy apatite to control the effect of decomposing andabsorbing the bacteria.
We will be glad to discuss with your detail technical request anytime.
Thank you in advance.
