TOKUSHIKI's core technologies are synthetic, dispersive, and compounding technologies, which combine to produce a variety of products. This site introduces the types and features of the developed functional dispersion liquid in which the characteristic functional materials are dispersed.
List of Products Developed and Characteristics
Inorganic fillers with distinctive functions, such as titanium oxide, barium titanate, and zinc oxide, can be dispersed into water-based or solvent-based dispersions to be added to paints, inks, coats, viscosities, and adhesives. The addition of functional inorganic filler dispersions to each product can be expected to develop the features of functional fillers.The functional inorganic-filler dispersions currently under consideration in TOKUSHIKI are as follows.
| Inorganic oxide species | Dispersion liquid (solvent system) | Dispersion liquid (water-based) | Intended use |
| TiO2（Titanium Oxide） | 9060TO | 9061TO | UV cut, high refractive index |
| BaTiO3（Barium titanate） | 9056BT | 9057BT | High dielectric constant and high refractive index |
| SiO2（Silica） | 9064SO | 9065SO | Scratch resistance |
| ZnO（Zinc oxide） | 9058ZO | 9059ZO | UV cut, heat dissipation |
| AlN（Aluminum nitride） | 9066AN | － | Heat radiation |
| ZrO（Zirconium oxide） | 9078ZR | 9079ZR | High refractive index |
| MgF2（Magnesium fluoride） | 9076MF | － | Lower refractive index |
| MgO（Magnesium oxide） | 9082MO | － | Heat radiation |
In addition to the above
・Kaolin
・Carbon nanotubes (CNTs)
・Graphene
・Conductive mesoporous carbon
And other dispersions are also being considered.
Expected use
Titanium Oxide (TiO2) dispersions
General type
Hidden, low viscosity, and high content are characteristic. The hues range from blue to yellow.Atomization type
The transparency can be increased because the refractive index of the particles becomes smaller even though the refractive index is high. Used in optical applications.(For short focal point, etc)Barium titanate (BaTiO3) dispersion
General type
It is characterized by high refractive index and high dielectric constant.Atomization type
Since the thickness of the capacitor can be reduced, miniaturization can be achieved by increasing the number of laminations.Because of its high dielectric constant, it is used to reduce noise in circuits.
Aluminum nitride (AlN) dispersion
It is characterized by high thermal conductivity and electrical insulation. It is used as a heat sink or printed circuit board.Kaolin dispersion
By mixing kaolin with paint, etc., it is expected to have effects such as hiding property (substitution of titanium oxide), gas barrier property, and mechanical strength.Conductive mesoporous carbon dispersion
It is expected to be a substitute for conductive carbon. It is characterized by good dispersibility and high blackness as the specific surface area is large. In addition, electrical conductivity can be achieved in relatively small amounts.It can be used as a substitute for activated carbon as a further alternative. Since the pore size can be adjusted, the target molecules can be captured efficiently.
Using the above two characteristics, we are actively studying the use of rechargeable batteries for high-speed charging.
It is also characterized by high efficiency as a carrier for the catalyst.
CNT/Graphene dispersion
Electrically conducting material. Depending on the content, it can be used as a transparent conductive film. It is also attracting attention now as a material for use in flexible devices and wearable devices. The conductivity is higher than that of conductive carbon, and the effect can be expected even by adding a small amount.In addition to the inorganic fillers introduced here, we have a distributed processing service that meets the needs of our customers.
Summary
TOKUSHIKI is developing dispersions in which inorganic fillers are dispersed, which have distinctive functions.The aim is to develop the characteristics of dispersions by adding inorganic filler dispersions to paints, etc.
In addition to the inorganic fillers described above, they can be dispersed according to your request.
