MCI - Model 2020 -Surface Applied, Migrating Corrosion
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.
MCI-2020/MCI-2020 V/O are organic corrosion inhibitors. They are considered ambiodic (mixed) inhibitors which means they protect both anodic and cathodic areas within a corrosion cell. MCI- 2020/MCI-2020 V/O contain a synergistic blend of amino-alcohols and salts of carboxylic acids which form a protective layer on embedded reinforcement delaying the onset of corrosion as well as reducing existing corrosion rates.
MCI-2020 and MCI-2020 V/O are recommended for:
- Preventative maintenance of existing reinforced, precast, prestressed, post-tensioned, or marine concrete structures
- Bridges, highways, and industrial floors exposed to aggressive environments (chemicals, deicing salts, carbonation, atmospheric attack)
- Parking garages
- Concrete piers, dams, offshore platforms, piles, pillars, pipes, utility poles, and cooling towers
- Concrete potable water structures
- As a component of Cortec`s High Performance Repair System (HPRS)
MCI-2020/MCI-2020 V/O offer engineers, owners, contractors, DOTs, and other government agencies a time proven, corrosion inhibiting technology that will extend the service life of their reinforced concrete structures.
