Cortec has introduced MCI-2018 V/O: a higher viscosity version of MCI-2018 sealer for vertical and overhead applications. This line of water repellants is composed of 100 percent active silane. MCI-2018 V/O is designed to chemically react with concrete surfaces to form a strong bond with the substrate. The product creates a hydrophobic layer, intended to repel water and keeps chlorides out without affecting the moisture vapor transmission of the concrete. The Migratory Corrosion Inhibiting (MCI) molecules contained in MCI-2018 V/O penetrate the pores to adsorb underlying metal reinforcement and protect from corrosion. MCI-2018 V/O has been tested by AMEC Laboratory and is certified to comply with Alberta DOT standards for type 1B and 1C penetrating sealer.
