Cortec MCI®-2020 Gel

Product Description

MCI®-2020 Gel is an injectable corrosion inhibitor which provides a robust dose of corrosion protection directly at the depth of steel reinforcement in concrete.

MCI®-2020 Gel utilizes the timeproven chemistry of Cortec’s Migrating Corrosion Inhibitor™ (MCI®) Technology to migrate to steel reinforcement from injection locations. Once at the reinforcing steel, MCI® molecules deposit across the metal surface to form a monomolecular layer which acts as a barrier to corrosive elements such as chlorides.

MCI ®-2020 Gel utilizes the same time-proven inhibitor formulation as the classic MCI®- 2020 liquid, but with added thickener to increase ease of use and reliability in injection applications

Packaging & Storage

MCI®-2020 Gel is available in 10.3 oz. (304 mL) caulking tubes, 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.

To ensure best product performance, store in original packaging, indoors, and out of direct sunlight at 40-100 °F (4- 38 °C).

Shelf life: 2 years

How it works

MCI®-2020 Gel is an organic corrosion inhibitor. It is considered ambiodic (mixed), meaning it protects both anodic and cathodic areas within a corrosion cell. MCI®- 2020 Gel contains a synergistic blend of amine salts of carboxylic acids which form a protective layer on embedded reinforcement, delaying the onset of corrosion and reducing existing corrosion rates.

By utilizing an injection application, MCI®-2020 Gel delivers active chemistry directly to the depth of steel reinforcement. At this depth, the inhibitor can move laterally through the concrete via aqueous, vapor, and interfacial diffusion along the embedded reinforcement

MCI®-2020 Gel is effective at extending the service life of concrete structures exposed to corrosive environments (carbonation, chlorides, and atmospheric attack).

Where to use

• Steel-reinforced concrete bridges exposed to corrosive environments (carbonation, deicing salts, and atmospheric attack)  
• Parking decks, ramps, and garages  
• Marine concrete structures, dams, and piers  
• Balconies, decks, retaining walls, and lanais  
• Structural walls and equipment bases  
• Below grade tunnels  
• Window lintels

Advantages

• Solves corrosion problems in areas where surface corrosion treatments cannot be used  
• Can be dosed to rebar depth, directly targeting problem locations and reducing time needed for migration of the inhibitor  
• Migrates to adjacent areas to protect metal
• Economical to install and maintain  
• Non-flammable, non-combustible  
• No secondary amines or nitrites
