NAOTECH Co., Ltd. was established in 2000 in order to develop, manufacture, and sell special paints. The major products include water repellent-coated wiper blades, special paints, and products for vehicles maintenance. For supplying products customized to meet customers’ needs, NAOTECH produces all of its products according to order.
For special paints, this company provides technical assistance for the entire process ranging from selection of products to coating, and thus helping clients in need of technology assistance.
NAOTECH sold its water repellent wiper to global companies in the United States, Japan, Canada, Europe, and South Korea. This was the first developed water-repellent wiper in the world and the company holds patents effective in five countries. And also it holds a number of patents in Korea. In an effort to ensure the quality of the products it produces, this company seeks to receive ISO certification from TUV, which is known as a strict certifier in quality specification.

NAOTECH’s water repellent-coated wiper blade reproduces high water-repellency. It boasts high-durability with guarantee of 200,000 times of use (about one year). This realizes more than 95 degrees contact angle of water drop (other products have less than 80 degrees.)
Some competitive technologies such as hydrophobic nano projections utilize the effects of lotus leaves, and surface treatment technology of nano-thin film coating is applied to this product, so moisture on an automobile’s windscreen can be swiftly removed.
By using an oligome (a kind of silicon and fluorine) and a nano carbon particle, this product overcame the flaws of the existing hydrophobic water repellency and obtained more than 95 degrees of contact angle of water repellency. This product thus significantly improved capability in terms of high water-repellency, flexibility, visibility, light penetrability, high water-repellency, and water-repellent endurance.

The high water-repellency wiping technology is a biological simulation technology performing an effect of lotus leaf. The basic factor of this technology is how to realize the hydrophobic nano projections and air pocket structure.
The effect of lotus leaf supports water drops like solid objects by numerous times of hydrophobic nano projections, and therefore the surface of the front door of automobiles is not wet with the rolling occurrence of water drops like a ball. Even in rainy situations, stains of dirty water are not spotted at all. Furthermore, the removal of the dust in the surface of front doors, foreign substances, and grunge is possible. Thus, the super-hydrophobic self-washing function, differentiated from the performance of the existing hydrophobic water repellency, is ensured.
