MCI®-2021 is a concrete sealer that combines a blend of reactive silicates, surface-active agents, and Cortec’s time-proven Migratory Corrosion Inhibitors (MCI®). MCI®-2021 preserves and protects concrete by working with the chemistry of concrete. The reactive silicates penetrate up to 11/2 inches (3.75 cm) in concrete and react with calcium. The reaction products build additional insoluble silicate structures within the concrete.
The newly built structure seals surface pores and creates a water repellent surface preventing carbonation and further intrusion of chloride. The concrete’s ability to breathe is not affected. MCI®-2021’s unique MCIs migrate through concrete structures to form a protective layer on embedded steel reinforcement. MCI®-2021 also protects a multitude of other metals including carbon steel, galvanized steel, and aluminum. MCI®-2021 will inhibit the further corrosion of reinforcing metals and extend the service life of the structure.
note: A UV tracer may be added upon request.
WHERE TO USE MCI®-2021
MCI®-2021 is recommended for repair and maintenance of:
- All reinforced, precast, prestressed, post-tensioned, concrete structures; including bridges, piers, highways, parking decks, ramps, garages, buildings, and streets exposed to corrosive environments (carbonation, deicing salts, and atmospheric attack)
- Plant floors subject to chemical attack
