Nanotechnology to Maintain Beauty, AD-Tech COAT
AD-Tech COAT is a water-based, 100% inorganic coating material made from silica and water, which are materials that make up the crust of the earth, and has a high antifouling property. By applying AD-Tech COAT, the surface of a base material is covered with a hydrophilic coating, thereby preventing the adherence of soiling on the base material. Soiling that adheres on the coating can be easily washed away with water.
Japanese and U.S. patents have been obtained. AD-Tech COAT is a Japanese-born harmless coating material, which does not contain organic substances (petroleum origin substances), carbon or volatile organic compounds. Its superior inflammability has been proved by the railway vehicle combustion test.

Features of AD-Tech COAT
Hydrophilic Cleaning Performance
High Cleaning Performance Utilizing Hydrophilic Property
The hydrophilic coating absorbs moisture content in the air. Soiling adheres on the coating. The coating contains moisture and when water is poured thereon, the soiling floats on the coating and is easily washed away with the water. Because of the water content in the coating, the buildup of static electricity can be prevented and therefore dust and particles are not attracted.

[Contact Angle Formed with Base Material and Water]
・Hydrophilicity: 40-50°
・Superhydrophilicity: 10° or less
[Contact Angle Formed with Base Material and Water]
・Water repellency: 90-110°
・Super water repellency: 150° or more
What is hydrophilicity?
Generally, hydrophilicity represents a state in which the angle of contact formed with water and the base material is less than 50°, while superhydrophilicity represents a state in which the angle is 10° or less.
※The contact angle may change depending on the surface condition of the base material.
Mechanism of Antifouling Coating
AD-Tech COAT is effective immediately after applying it on the base material. The coating material absorbs the moisture content in the air and creates a water film thereon.
Since the base material is covered with the water film, soiling will not adhere to the base material directly.
When rain falls onto the coating, the rain mixes with the water film and soiling is released from the water film.
If the rain fall continues, the soiling will be washed away with the rain.
Long-life Coating
Long-life Coating
AD-Tech COAT does not contain any compounds that are deteriorated by exposure to ultraviolet rays. Unless the base material deteriorates, the layer of AD-Tech COAT will not peel off. Since the coating is flexible and does not harden, it resists abrasion, such as through cleaning. Even if a vehicle washing machines are used, the coating on a public transportation vehicle will not peel off. The water content contained in the coating decreases the coefficient of friction and increases the abrasion resistance.
Applicable to Various Materials
| Metal base material | Aluminum, magnesium (stainless steel), etc. |
|---|---|
| Resin base material | Plastics, decorative laminated sheets, FRP, etc. |
| Organic base material | Paint, lacquer-coated surfaces, etc. |
| Inorganic base material | Glass, marble, tiles, sanitary ceramics, enamel, etc. |
Applicable to Various Materials
Since AD-Tech COAT is a water-based, 100% inorganic coating material, it can be applied on any material.
Maintenance of Permeability
Maintenance of Permeability
Since the particle diameter of silica is very small and its refractive index is lower than glass, the light transmittance of the base material is not compromised by applying AD-Tech COAT.
