Aqueous Fully Inorganic Coating
PicaPica COAT

Pica Pica Coat is the world first coating material composed with a water-based fully inorganic material. Stains will come off by pouring water, and the coat is workable for semi-permanently. Pica Pica Coat is environment friendly and easily manageable. Therefore, it is applied to a variety of objects from road structure such as an expressway and tunnel to domestic products such as a solar panel, car, and bathroom.

A Coating Material coming off only by pouring water!

You only need water to get a bright result! Cleaning will never be a painstaking job and you can cut payrolls for that. Pica Pica Coat can shorter the time for site operation and not require extensive work. Furthermore, this odourless and non-toxic coating assures safety.

Appeal of Pica Pica Coat

1

Hydrophilicity and Antistatic Performance

The coat has hydrophilic character which means to be resolved into water easily, which enables to equip self-cleaning function by rain and shower. In addition, it does not leave water drops on the surface and stains because of its lens effect. Oil stains are also removable with water. Furthermore, its antistatic effect keeps dust away.

What is Hydrophilicity?
– Hydrophilicity and Water repellency –

The angle of contact between the base and water changes by the condition of its surface.

Durability and Weatherability

Containing no chemical compound which deteriorates by the ultraviolet radiation, the coating sustains unless deterioration of the basis happens. Under the weather-proof test, it is maintained for more than twenty years without any deterioration and color fading from ultraviolet rays. The coating is preserved after the powerful brushing by the railway car washer. Furthermore, it works well in the hostile environment such as areas with chloride attacks and a factory neighborhood.

Siloxane Bond

Porous SiO2 covers the whole surface of inorganic base.

Safety

The coating is a fully inorganic material being consist of silica and water, which means it is free from surfactant, solvent and alcohol. It does not apply to the PRTR law, and it causes neither soil nor water contamination. In addition, the coating does not corrode cradles and metal frames. Not volatile, odorless and harmless. Since it is nonflammable, you can work safely without worries of ignition and explosion.

  • No environmental risk
  • No metal erosion
  • No volatility
  • No risk of explosion and ignition

Mechanism of Antifouling System

The coating generates irregularities on the surface and absorb water in the air. The water works as another layer on the indents, and stains remain on the layer. Showering over the layer, the watery layer swells and removes stains altogether.

After coating a base material, it absorbs the moisture in the air and creates a watery barrier on the surface immediately. Therefore, no static electricity is generated.

Since the surface of the material is protected by the barrier, stains and dirt will float on the watery layer.

If it rains on the material or you shower over it, that water will be bound with the existing watery layer. Thus, the stains will be kept further away from the surface.

Additional rain or shower on the material will remove the stains and dirt along with water.

Used for Diverse Purposes
from Infrastructure to Household Applications


Road, Tunnel & Bridge

Use Pica Pica Coat for protecting road signs and signals from dirt and snow. The coating has self-cleaning function, and the maintenance will be easier. It can be applied to a tunnel; you can prevent dirt and remove it with high-pressure washing. Moreover, the extremely thin and clear coating does not affect the illumination in the tunnel. Take measures for salt erosion with Pica Pica Coat. Because of the hydrophilic barrier, the salt will flow down by rain.

Car

With the coating, the dusts and dirt on your car will be wash off easily by rain and shower. There will be no water scale so that you do not have to wipe up the car anymore. The coating works greatly for various parts such as wheels, a bumper, headlights, a hood, and back mirrors.

Solar Panel

Dirt on solar panels will cause cluster deficits and hotspot effects that leads to the significant reduction in electricity generation. Thus it is ideal to clean them up in the early phase, it is impractical to deal with it every time. However, it will be much easier by the coating which can remove the dirt in synergy with the rain.
In addition, that increases transmission of the panel glasses; that hugely contributes to the rise in the electricity generation.

In the House

Protect your devices from grimes, finger marks and static electricity. You can also apply the coating to a lavatory, bathroom, a window, and many other places at home.
