Functions of antifogging coating:

1 Super hydrophilic self-cleaning function:anti-fogging coating also uses super hydrophilic silicon oxide film to form a super hydrophilic film between the painted surface and dirt, so that dirt and coated surface separation and the use of natural rain wash away the stolen goods under the action of gravity, to achieve the purpose of self-cleaning.

2 Antistatic function:antifogging coating can be for the domestic air quality is not good, serious pollution, adding Mitsubishi chemical nanomaterials, antistatic, do not absorb dust and particles in the air, dust, waste gas is also difficult to adhere to the brushing surface.

3 Decomposition oil function:antifogging paint can be used for automobile exhaust, factory and hotel emissions of smoke pollution, adding TiO2 below 5 nanometers, strong decomposition paint stains attached to the coating surface

Principle of antifogging coating:

Fog is caused when hot air hits cold objects and condenses into small water droplets on the surface. Light is diffused across the surface of these droplets, giving the impression of fog.

Therefore, antifogging should prevent the formation of small droplets antifogging coating on its surface has super hydrophilic, which increases the surface tension of water water can not form droplets on its surface, but a layer of water film, fundamentally prevent the formation of mist.
