DEFENDAIR™ 200C Air and Weather Barrier Coating

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.

用途:

Strong adhesion strength to common wall substrates, including:

  • DensGlass
  • Concrete masonry units (CMU)
  • Oriented Strand Board (OSB)
  • Plywood
  • Exterior Sheathing
  • Preformed Panels
  • Steel stud walls
  • Rainscreens

优势:

  • Airtight performance that exceeds industry standards
  • Passes NFPA 285 assembly testing
  • Improved shelf life
  • Aesthetically pleasing charcoal gray color
  • Reduced appearance of dirt pickup
  • Improved energy efficiency and durability
  • Can be applied at temperatures as low as 20°F (-6°C)
  • Long-term UV resistance and enhanced weatherproofing
  • Water-based, low-VOC formulation 
  • Vapor-permeable and breathable
  • One-coat spray application; may also be roller applied
  • Primerless adhesion to even the most challenging construction substrates
  • Complete offering of compatible accessory materials
