\r\n\uff082\uff09Hydrophilic Properties<\/p>\r\n
\r\n\r\nHydrophilicity means that material with a special affinity for water. In the case of photocatalyst, the coating surface easily becomes wet, therefore, when the coating surface gets wet with rainwater, it gets under the \"dirt\", and the dirt floats up and the dirt runs down.<\/p>\r\n
Since the water on the surface spreads thinly and forms a film of water, it also has an anti-fog effect.<\/p>\r\n![\"Photocatalyst](\"https:\/\/www.palccoat.com\/en\/wp-content\/uploads\/hydrophilic_subimg.jpg\")

\r\n\r\nWhat is Titanium Dioxide?<\/h2>\r\n
Titanium dioxide is a white powder (superfine particles) that has long been used as a white pigment. It is used for a wide variety of usages such as in coatings, dental material, toothpaste, and cosmetics. It is also used as a food additive for coloring in white chocolate, sweets, and chewing gums because it is tasteless, odorless, and is harmless to humans.<\/p>\r\n<\/div>\r\n

Organic substance is a compound containing carbon that consists of carbon and oxygen (other than carbon monoxide and carbon dioxide). Organic substances include not only plastics, wood, and paper, but also pollutants that cause stains and odors, bacteria, viruses, mold, harmful volatile gases (VOCs), and Nox and Sox that cause air pollution, those are also organic substances (organic compound).<\/p>\r\n<\/div>\r\n
