Polyurea Waterproof Protective Coating Concrete For Bridge Piers, Hydropower Station Dam
Product Description
Bridge is a long range program and fundamental infrastructure, security issue is a most priority. As the support of bridge, only stable piers can make the bridge safe. Cross-sea bridge located in complex corrosive circumstance and wet climate is vulnerable to erosion, serious safety issue will occur if no high effective protection.PSCM-0360 is an ideal material with high performance of resistance to wet, seawater immersion and cathodic disbonding, good cohesion to the substrate.
Polyurea's ability to outlast paint and fight off corrosion is a major reason these systems are being specified for bridge deck and structure coating. The most common applications of polyurea coatings on bridges are over steel and concrete.

Characteristics
The coating for marine oil drilling platforms should fit for the marine environment and has the same service life with the platforms. The product has high reactivity, could spray-applied forming on curved,slope and vertical surface without sagging. It’s flexible, dense without seaming, high adhesion and impact resistance. It’s resistant to seawater and salt mist,wear resistant,anti-aging, enduring temperature from -40-120℃. No peeling and cracking when long term immersion in the seawater, no pulverization against the collision in marine atmosphere. The coating could help the platforms achieve a service life of 50 years above.
