Manufactured by: Dow Corning
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.
