QUICK OVERVIEW
VaproBond™ 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 ft2 (0.56-0.74 m²)/sausage
- Sealant: 125 lin.ft/sausage
Compatibility
- Concrete
- Masonry
- Natural stone
- Structural sheathing
- Painted Metals
- Glass
- PVC
- FRP
- EPDM
- Dry wood
- Architectural Metal Panels
- Most building materials, urethane, and acrylic sealants and coatings
