Although concrete structures are strong and practical, they are inherently porous and will allow the penetration of potentially destructive vapors and liquids. Concrete covers are often used for process vessels and storage tanks. Acid vapors can condense on the surface of the exposed concrete and quickly react with concrete components. Chloride ions can attack the underlying reinforcing bars eventually causing the concrete to spall. Concrete walls and floors must also be protected against such chemical attack.
STEBBINS Urethane Concrete Sealer (UCS) is a one-component, low viscosity sealer that penetrates and protects concrete from chemical splashes or harmful process vapors. Because it is based on a moisture reactive polyurethane resin, no catalyst is required. The resin simply reacts with moisture in the surrounding air to form a chemical resistant polymer. Once within the concrete, the urethane forms strong chemical and mechanical bonds.
