Anti-static Super hydrophilic Self-Cleaning coat

Development the Super Hydrophilic Coating with Anti-static
To understand the anti-fouling problems of fluorine and photo catalyst solution which are used to major anti-fouling coating, wedeveloped the new idea of anti-fouling in order to solve this problem.
We considered that the dirt does not adhere is important for anti-fouling coating, “Reduce the adhesion of dirt and easy to cleanup” is our theme to develop new antifouling coating. Our antifouling coating, it prevents to adhere the inorganic dirt such as yellow
sand and carbon with antistatic function as much as possible, and clean up the dirt with photo catalyst whether there is light or not.
This product has 100% inorganic ,anti-static and super hydrophilic effect. Antifouling coating is suitable for the outer wall andmaterials, also on the painting.
The inorganic adhesion binder with tin oxide reduce the fouling of yellow sand and carbon in the antistatic effect. It does not mean
to reduce the dust completely, but it could reduce the dust as much as possible like a clean room. Rather than porous as titaniumoxide, silica SiO2 can reduce the adhesion of dirt to form Nano-size a uniform uneven surface. The function of the inorganic
adhesion binder, and Nano-sized irregular surface on fractal theory ※ to form a permanent super hydrophilic film whether there islight or not. When it rains the water enter the Nano-sized uneven surface to take off the dirt. Eve cleaning becomes easy.

※Fractal theory

Effect of the hydrophilic can be improved by fine unevenness of the surface.
Unevenness lines uniform becomes a super water-repellent status;on the other hand, it lines unevenly becomes super-hydrophilic status

Various causes of pollutants and dirt in the air
The main contaminants of the exterior window panes are the combination of dust, yellow sand, carbon from the exhaust gas, pollen,soot and so on.
The window panes should not get fouled the dust easily, and require as few cleaning as possible. At the window panes for high-risebuildings where daily cleaning is not possible, The self-cleaning function by the rain is the most required factor. The necessity for as few
cleanings as possible is even more important, since cleaning cost of high-rise building is very costly.
In China, Southeast Asia and Middle East countries, there are many buildings with glass walls. As the labor cost is expected to rise in
the near future, by applying anti-static and anti-fouling coating while the labor cost is relatively inexpensive. The cost of cleaning andmaintenance in the future will be reduced greatly.

Requirement for Anti-fouling coating?
・Reduce the adhesion of dirt, also easy to fall attached dirt
・When compared to the cost of cleaning, there is a merit of cost・High-transparent and does not impair the texture of the base material
・Inorganic 100%, there is a chemical resistance, excellent durability and environmental resistanceThe Problem of a photo catalyst coating
Photo catalytic antifouling coat effects the dirt of organic gathered on the surface of the porous decomposed byultraviolet rays. Also, drop the dirt in the rain water by hydrophilic function. China and Southeast Asia is the dirt ofinorganic sand and carbon.
Photo catalyst coating decomposes dirt of organic, but it can not decompose the dirt of inorganic. So, it will dirty
more by collecting dirt on the surface of the porous. In addition, decomposition and the hydrophilic function of theorganic matter in the ultraviolet light can not be exhibited.

Issues of fluorine coat
Fluorine-based antifouling Coating has been used, it is an issue that
antifouling effect does not perform as it expected although it is expensive.
Fluorine-based coating has an excellent chemical resistance, good
weather resistance, and environmental resistance, there is a feature to beeasy to clean the attached dirt. But, it does not has a function to reduce
the adhesion of dirt.
It is charged and can not be suppressed the adhesion of dirt, because thecoat surface becomes water repellent, and stand out the dirt of a drop
water and rain dripping mark.

In addition, the fluorine-based coating is weak to ultraviolet light becauseof organic material, and aging degradation.

Reduce the dust as much as possible with antistatic effect!!
What is anti-static?
When the surface of the substrate is charged (Charged electrostatically), and then electric is sticking with other materials andparticles, such as dirt, dust and sand in the air.
Antistatic is easy to flow electricity to reduce the volume resistivity.
Since the anti-static material is discharged into the air and can be reduced to accumulate static electricity, it is possible tosuppress the adhesion of dirt, dust and sand caused by static electricity or the like.

Super hydrophilic means less than 10 degree of water angle to the substrate.
Water droplets remain as they are on the untreated surface, But they will seep into the layer under the fouling on
the hydrophilic surface, thus removing it. The water-repellent surface only repels the water, and has no function toclean itself.

Creating an even on the surface of the glass by using 100 to 200 Nano-sized silica, unlike the super-hydrophiliceffect of the photo catalyst, it can make a constantly super-hydrophilic film without the irradiation of light. Contact
angle is 5 degrees or less , so the rain or water enters the bottom of the dirt and it washes away the dirt.
