Problems solved by technology

[0002] The waterproof film formed after the waterproof coating is cured has certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance, and can play the role of waterproof, anti-seepage and protection. It is an indispensable material in civil engineering construction. And it is widely used in construction, highways, bridges and other projects. Most of the waterproof coatings currently on the market need a period of solidification time after spraying, which leads to a decrease in construction efficiency. Therefore, a method is proposed to address the above problems Production method of waterproof coating
