Description
Dow Corning® DefendAir 200 is a 100% silicone liquid applied Air and Weather Barrier designed to protect against air infiltration and water penetration. The vapor permeable, one component, water-based coating cures to form a flexible membrane that is impervious to water but has the ability to “breathe,” allowing water vapor to escape from inside the substrate.
