Problems solved by technology

[0002] Organic waterproof coating is a new type of polymer waterproof coating. It has been widely used in waterproofing projects because of its excellent physical and chemical properties such as good wear resistance, corrosion resistance, chemical resistance, high hardness, and high elasticity. However, a lot of organic solvents are added in the process of preparation and construction of traditional solvent-based waterproof coatings, which poses a great threat to human health and environmental protection. Free polyisocyanates in organic waterproof coatings are harmful to skin, Eyes and respiratory tract have a strong irritating effect, and long-term exposure can cause chronic bronchitis and other diseases. Therefore, we propose an organic modified waterproof coating
