Descriptions
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. SWD9011 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 by State DOT's around the nation. The most common applications of polyurea coatings on bridges are over steel and concrete.
Characteristics
The product has high reactivity, could spray-applied forming on curved,slope and vertical surface without sagging. Dense and seamless coating fully isolates the moisture and oxygen in the air, perfect adhesion to piers. Resistant to acid, alkali, salt mist, sea water, cathodic disbonding. Anti-aging, no bubbles, cracking, peeling and powdering when long term use in damp circumstances, weather resistant.
