Cortec expands line of water repellants

July 27, 2011

New sealer is suited for bridge supports, garage pillars and building walls.

Cortec Corporation, St. Paul, Minn., has introduced MCI-2018 V/O water repellant, a higher-viscosity version of its MCI-2018 sealer for vertical and overhead applications.

According to the company, its new line of 100 percent active silane water repellants chemically reacts with concrete surfaces to form a strong bond with the substrate. The sealer contains corrosion-inhibiting molecules that penetrate pores to create a hydrophobic layer that repels water and keeps out chlorides without affecting the moisture vapor transmission of the concrete, Cortec said.

MCI-2018 V/O can be applied by spray, brush or roller. Increased viscosity makes the sealer ideal for bridge supports, garage pillars or building walls. MCI-2018 V/O also dries without affecting the appearance of the surface, according to the company.

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.
