Cortec MCI-2020 hardened concrete corrosion inhibitor


MCI-2020 is a surface applied, migrating corrosion inhibitor designed to penetrate through cementitious materials including concrete, mortar, and limestone. MCI-2020 migrates in both liquid and vapor (gas) phases through the pore structure, forming a protective, molecular layer on embedded reinforcement. MCI-2020 provides corrosion protection against carbonation, chlorides, and other contaminants. MCI-2020 V/O is a high viscosity version of MCI-2020 which is specifically designed for vertical and overhead applications.
