QUICK OVERVIEW

hagen 160813 0111 editweb2VaproBond™ is a single component 100% silicone sealant used to bind layers of VaproShield membranes to each other or typical construction material surfaces. It can also be used as a liquid-applied flashing component with metal framing systems.

  • UV stable, black silicone sealant and all-weather flashing material
  • Binds layers of VaproShield membranes and other typical construction materials
  • Creates watertight and airtight details
  • Applies in -20° (-6° C) and above
  • No primers, easy to gun and apply

Benefits

  • No primer, easy to gun and apply, offers excellent weatherability
  • Allows for liquid flashing in below freezing temperatures
  • Binds layers of VaproShield membranes to each other and other building materials, creates a watertight, airtight seal
  • Simplifies process of producing watertight, airtight details
  • Remains flexible and pliable in extreme temperatures
  • UV stable, black silicone-based adhesive sealant
  • Meets or exceeds ASTM-C- 920 type S, Grade NS, Class 25
  • Flashing Coverage: 5-8 ft(0.56-0.74 m²)/sausage
  • Sealant: 125 lin.ft/sausage
