Cortec Injectable Corrosion Inhibitor

MCI®-2020 Gel is a successful alternative to topical treatments, providing a robust dose of corrosion protection directly at the depth of steel reinforcement in concrete.

MCI-2020 Gel from Cortec® Corporation is an injectable corrosion inhibitor that provides a robust dose of corrosion protection directly where it is most needed. It can be used in almost any concrete repair or maintenance application where it is deemed preferable to inject Migrating Corrosion Inhibitors rather than apply them as a surface treatment. These applications include any structure in a corrosive environment (carbonation, deicing salts, atmospheric attack), such as parking decks, ramps, and garages; marine structures, dams, or piers; building facades and window lintels; structural walls and equipment bases; and below grade tunnels.injectable corrosion inhibitor

Mitigating corrosion of embedded rebar is a perennial problem for reinforced concrete structures, requiring preventative maintenance and repair. Topical corrosion inhibiting treatments require a clean, properly prepared surface area to work as intended.

MCI-2020 Gel is designed to work when proper surface preparation cannot be achieved or is economically undesirable, by delivering Cortec’s Migrating Corrosion Inhibitor™ (MCI) Technology directly to the depth of reinforcement. Once inside the concrete, the injectable corrosion inhibitor can also move laterally through the concrete along the embedded reinforcement via liquid and vapor diffusion. MCI® molecules deposit across metal surfaces, forming a molecular layer that acts as a barrier to corrosive elements such as chlorides and carbonation.injectable corrosion inhibitor

MCI-2020 Gel is considered a mixed inhibitor that protects against corrosion at both the anodic and cathodic areas of a corrosion cell. This injectable corrosion inhibitor does not contain secondary amines or nitrites, which together can form carcinogenic nitrosamines. It is also non-flammable and non-combustible.

MCI-2020 Gel utilizes the same inhibitor formulation as the classic MCI®- 2020 liquid, but with added thickener to increase ease of use and reliability in injection applications. It is available in 10.3 ounce caulking tubes, five gallon pails, 55 gallon drums, liquid totes, and bulk.

To ensure best product performance, MCI-2020 Gel should be stored in its original packaging, indoors, and out of direct sunlight at 40°F to 100 °F. Shelf life is two years.
