Additional Product Information
Overview
PR-1826A-1/2 (1-S654) is a high-performance aircraft integral fuel tank sealant developed for demanding aerospace applications. This rapid-cure sealant is formulated with Permapol P-3 polythioether, providing robust elastomeric properties and exceptional resistance to jet fuel and aviation gasoline. Its wide service temperature range and durability make it well suited for critical fuel tank and fuselage sealing tasks where safety and reliability are essential.
Key Technical Specs
- Sealant Type: Rapid-cure, polythioether-based aircraft sealant
- Formulation: Permapol P-3 polythioether for durability and chemical resistance
- Service Temperature Range: -80°F (-62°C) to 320°F (160°C); intermittent excursions up to 420°F (216°C)
- Cure Characteristics: Capable of curing at low temperatures; unaffected by humidity changes
- Adhesion: Excellent adhesion to aircraft substrates when used with PR-1826AP Adhesion Promoter
Typical Aircraft MRO / AOG Applications
- Fillet sealing of aircraft integral fuel tanks
- Sealing applications throughout the aircraft fuselage
- Fuel containment areas requiring long-term elastomeric performance
- MRO and AOG repairs where rapid cure and fuel resistance are critical
Performance Characteristics
- Maintains elastomeric properties under prolonged exposure to aviation fuels
- Excellent resistance to jet fuel and aviation gas
- Designed to support structural integrity through reliable fuel-tight sealing
Compatibility & Usage Notes
