PR1422B2 is a high-performance, two-part polysulfide sealant developed specifically for aerospace fuel tank and structural sealing applications. It is widely used by aircraft manufacturers and MRO facilities due to its outstanding resistance to aviation fuels, oils, and hydraulic fluids.

This sealant provides excellent adhesion to aluminum, composites, and other aircraft substrates while maintaining flexibility after curing. Its Class B-2 formulation offers a balanced application time, making it suitable for both production and maintenance environments.

PR1422B2 cures to a durable, elastic rubber that resists cracking, vibration, and temperature fluctuations. It is commonly used in integral fuel tanks, fuselage sealing, and wet-wing applications where leak prevention and long-term reliability are critical.
