A superior seal amid aerodynamic heating

A reliable seal is crucial for aircraft fuel tanks, especially when aerodynamic heating causes fuel and fuel vapours to expand and create internal tank pressure. Swelling slightly upon exposure to common fuels and tightening the seal during service, DOWSIL™ 94-031 Fluorosilicone Channel Sealant offers key benefits for ensuring a superior seal in aircraft fuel tank groove injections. This sealant provides good tack adhesion, maintains consistency over a wide temperature range—from -55°C to +200°C—is essentially unaffected by shock, vibration and thermal cycling, contains no catalyst or curing agent, and is easily injected and reinjected directly by air gun into the grooves of integral fuel tank systems during fabrication or maintenance.
