Product Description
Polyurea coating is suitable for all concrete surfaces, metal tanks and internal and external surfaces of the national key projects, "two anti-one resistance" (waterproof, anti-corrosion, wear-resistant) sub-project, has been widely used.
The industrial heavy-duty polyurea coating is continuous, dense, pinhole-free, seamless, and has a large film thickness at one time, thus exhibiting excellent heavy-duty performance under harsh environmental conditions such as acid, alkali, salt, underground and ocean. . With advanced construction technology, the material has broad application prospects in the fields of chemical storage tank lining, tunnel, marine steel structure and concrete structure.
