more info
Dow Corning Q4-2805 fluorosilicone channel sealant is as a groove injection sealant for aircraft fuel tanks. It can also be used in applications that require a non-curing sealant. During tank fabrication or maintenance, this sealant is directly injected by an air gun into the grooves of integral tank systems. - When exposed to aviation fuels, this channel sealant will swell just enough to tighten the seal. This is a useful characteristic especially when the expansion of fuel and fuel vapors might cause internal tank pressure, which can happen as the result of aerodynamic heating.
Features
- Superior sealing characteristics under exposure to fuels and oils
- Easily injected and reinjected
- Maintains consistency over wide temperature range from -55 °C (-67 °F) to 200 °C (392 °F)
- Non-curing
- Good tack adhesion
- Essentially unaffected by shock, vibration and thermal cycling
- Contains no catalyst or curing agent
- Withstands immersion in fuels and exposure to fuel vapors in temperatures up to 200 °C (392 °F)
- Contains flow-control particles
- Excellent flow characteristics provide faster injection at reduced pressures
Applications
- For used as Groove Injection Sealants for Aircraft Fuel Tanks
