The reinforced concrete structures in the municipal engineering will crack on the surface because of the thermal expansion and cold contraction influence, and then the humidity from salt spray, acid rain, oxygen of air will rust the concrete gradually along with the cracks. When the erosion deeps down the reinforced concrete internal structure and destroy its construction property over time, the capability and construction strength of reinforced concrete structure will be change and weak. It will even risk the livelihood security of the resident. The water base municipal engineering special reinforced concrete anticorrosion coating is developed by SWD Urethane Co., USA in the 1990s, the coating film is dense, flexible, effectively protect the concrete from crack and corrosion. It has been widely applied in the reinforced concrete structures protection projects in the Europe, America and the East Asia regions.
Characteristics
Applied with unique formula, taking one component environment friendly water base polymer and high quality nano materials as main raw materials, this product is refine produced from scientific process that has UV stable monomer structure and special functional groups of high adhesive strength and anticorrosion protection. The coating film is dense, with excellent sealing and anti-permeability performance and high adhesive strength with substrate, high properties of acid and alkali and oil resistance, salt spray resistance and waterproof, anti-mildew as well as chemical resistance. One component water base product, easy to apply, green and eco friendly, with no harmful violate gas during application. It is environment friendly product that will do no harm to environment and human health.
