Dow Corning Q4-2805 Fluorosilicone Channel Sealant is primarily used as a groove injection sealant for aircraft fuel tanks. It is also suitable for various sealing applications that require a non-curing sealant. The sealant is injected directly by air gun into the grooves of integral fuel tank systems during fabrication or maintenance. Upon exposure to common fuels, this sealant will swell slightly, tightening the seal during service. This characteristic is especially beneficial when, as a result of aerodynamic heating, expansion of fuel and fuel vapors may cause internal tank pressure.
