Superhydrophobic Polyurethane Coating

Product Introduction:

The most common measure of wetting behavior is the static contact angle. The static contact angle is the angle formed between liquid and solid in the region of the three-phase boundary. The size of this angle depends on several factors, including surface free energy, surface roughness, and surface cleanliness. If a drop of water makes a contact angle smaller than 90° with a solid surface, it will wet the surface, and that surface will be hydrophilic. If the size of this angle is within the range, the surface will not be wetted, and the surface will be hydrophobic. The contact angle of water on superhydrophobic surfaces is very high (more than 150°), and the drop on them takes shape similar to a perfect sphere. Due to the low adhesion of the water drop to these surfaces, the drop easily rolls on them even on low slopes and cleans the surface pollution along with it.

Among the uses that these colors can have is in electricity distribution network lines. Concrete foundations are one of the most widely used components of the electricity distribution network, whose optimal structural performance is essential.

One of the factors of the unreliability of concrete is the inappropriate surrounding conditions, such as the presence of sulfates and salts around the concrete structure and corrosion of steel due to the penetration of harmful chemicals and moisture in steel concrete structures. Using ultra-hydrophobic coatings can solve this problem due to their accessible cleaning properties. Due to their super waterproof properties, these covers can be easily washed by rain or wind, preventing the accumulation of pollution on the surface and completely removing water from their surface. Polyurethane superhydrophobic coatings have superhydrophobic properties and have shown good weather resistance. Compared to commercial polyurethane coating, these coatings reduce water absorption to the surface by 80% and reduce the adhesion of moss and surface pollution.
