Sealants
PR-Type Sealants
General Overview
Functions of Sealants
Sealing
Fuel sealing
Air sealing
Fuel tanks (fuel leaks)
Fuselage bays (pressurization)
Functions of Sealants
Electrical insulation (lightning strike)
Galvanic sealing
Differences in electrical potential between materials generate corrosion when they are in contact.
Functions of Sealants
Protecting against corrosion
Ensuring fatigue resistance
Through the anti-fretting (no friction between bonded parts)
Corrosion example
Functions of Sealants
Draining at the lowest point of tanks Preventing water retention by filling cavities
Functions of Sealants
Improving aerodynamics Filling panel joints on fuselage – wing
Different Sealant Applications
The sealant selection for the required application is specified in the work card.
