Cortec has expanded its MCI portfolio to include MCI-2018 X, a 100% silane penetrating water repellent for concrete surfaces. MCI-2018 X is MCI-2018 minus the Migrating Corrosion Inhibitors.
Its primary function is to line concrete substrate pores with a hydrophobic layer that reduces the ingress of moisture, chlorides and carbonation, extending the service life of the structure. If applied after a penetrating SACI (surface applied corrosion inhibitor), MCI-2018 X prolongs the protection period of the corrosion inhibitor. MCI-2018 X allows the surface to stay breathable and retain its original appearance.
Concrete Solutions
MCI-2018 X can be used for routine maintenance every five to 10 years or used as part of the finishing touches to a concrete repair. Because it does not change the substrate’s appearance, MCI-2018 X serves as an option for historical restorations. As a silane water repellent, MCI-2018 X has small molecules and adsorbs into concrete for areas where slippage is a concern (e.g., steps, parking garage floors and bridge decks). Other target applications include commercial buildings, tunnels, jetties/piers and offshore oil platforms (non-submerged applications).

Application
MCI-2018 X can be applied by spray, roll or brush to a clean concrete surface with a CSP 1-3 surface profile (per ICRI guidelines). MCI-2020 may be applied first for additional corrosion protection. After a repair, fresh concrete should be allowed to cure 28 days before application of MCI-2018 X. A dry surface is preferred for maximum penetration, although the second coat of MCI-2018 X should be applied wet-on-wet over the first coat for best results.
