DOWSIL DefendAir 200 is a 100% silicone liquid applied Air and Weather Barrier designed to protect against weather 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 the water vapor to escape from inside the substrate.

UV Resistant- long term resistance. Provides long-term air and water protection properties even when exposed to sunlight, rain, snow or temperature extremes. Ease of installation- one coat installation. Air tight- exceeds industry requirements. Primerless adhesion to most substrates. Elastomeric- accommodates building movement. Seamless- cured membrane is continuous and does not form seams or laps.

Permeable air barrier used for new construction and renovation applications on several substrates including concrete, OSB, exterior sheathing, preformed panels, plywood, wood or steel stud walls.
