PPG PR 1422 B1/2 FUEL TANK SEALANT 6OZ 654 SEMKIT PR1422B1/2

PPG® PR1422 B1/2 Fuel Tank Sealant in the 6 oz 654 Semkit® combines a manganese dioxide–cured polysulfide base with fast application and cure characteristics tailored for efficient production and maintenance work. Engineered for sealing integral fuel tanks, wet wings, and fuselage structures, it adheres to aluminum, composites, and coated substrates while retaining elasticity under pressure, vibration, and temperature shifts. Its cured matrix resists sustained exposure to jet fuel, oil, and hydraulic fluids, preventing leaks and corrosion in demanding flight environments. The short work life supports rapid assembly or field repair where minimal downtime and long-term sealing reliability are critical.
