MCI-2020 Gel is the Cortec’s Solution for Corrosion Protection of Metal Reinforcement To ensure durability of concrete structures, Cortec has developed MCI-2020 Gel, an injectable corrosion inhibitor which provides corrosion protection directly at or near the depth of steel reinforcement in concrete.
