How Cortec MCI® 2020 M, a Migrating Corrosion Inhibitor Designed, Works

The mechanism behind Cortec MCI® 2020 M’s remarkable performance is rooted in its ability to actively migrate through the concrete and form a protective layer on the surface of the galvanised steel reinforcing bars embedded in metals. It also protects carbon steel stainless, enhancing the longevity and durability of these metals embedded in concrete structures. This process is facilitated by the product’s unique chemical composition, which allows the corrosion inhibitors to travel through the porous concrete structure and reach the critical areas where they are needed most, including steel reinforcing bars.

Once the corrosion inhibitors have formed a protective layer on the embedded reinforcement, galvanised steel, and aluminium together, they create a barrier that prevents the ingress of harmful substances, such as chlorides, oxygen, and corrosive agents, which are the primary drivers of corrosion. This proactive approach to corrosion prevention ensures that the reinforcing galvanised steel and aluminium remains protected, even in the face of the most challenging environmental conditions.
