The main function of the overpass is waterproof and anti-corrosion. However, in the relatively harsh outdoor environment, the general paint will peel off and peel, which will not only damage the appearance of the overpass, but also directly affect the life of the overpass.
Polyurea coatings have superb abrasion resistance, aging resistance, corrosion resistance, scratch resistance and other functions, and have strong adaptability to the construction environment. Since polyurea reacts very fast at room temperature, water molecules in this system have no time to react with isocyanate, so the humidity around the environment will not adversely affect the quality and surface of the coating. This avoids the humid environment problems often encountered in the construction of polyurethane waterproof coatings, and facilitates the construction.
