Coating PET Antifogging Film Roll For Protective Mask Thermoforming

Hydrophilic to assume an object’s surface hydrophilization anti-fog coating, reuse anti-fog coating of hydrophilic group factor was carried out on the water affinity adsorption, and reduce the surface tension of the water and reduce water molecules and the contact Angle on the surface of the object, the water vapor is not before the surface gathering into small water droplets, will be adsorbed on the surface, wettability, diffusion or form a thin layer of transparent water film, and no longer on the incoming light scattering effect, without interfering with the line of sight of people, so as to achieve the goal of prevent mist.

Hydrophobic anti-fog coating surface is hydrophobic, anti-fog coating in the hydrophobic group factor and reusing water molecules repel each other, increase the water molecules and the surface contact Angle and moisture on surfaces gradually condense into each one has a large contact Angle of water droplets is difficult to stay on the surface, will continue to drop automatically (that is, produce the «lotus effect»), so as to achieve the goal of prevent mist or waterproof.Due to hydrophobic anti-fog coating is the use of the «lotus effect» to achieve prevent mist, so with the falling of water droplets, the surface will leave some irregular water mark, the water mark can produce some of the incoming light scattering effect, more or less to reduce the light transmittance of the object, affect the person’s line of sight, with the variation of anti-fog effect and has limitations.
