PPG PR1440B2-1001 (100-ml-Semkit)

Additional Product Information

Overview

PPG PR1440B2-1001 (100-ml Semkit) is a high-performance aircraft integral fuel tank sealant engineered for demanding aerospace environments. This two-part, manganese dioxide-cured polysulfide sealant is specifically designed for fillet sealing of fuel tanks and critical fuselage applications. It cures at room temperature to form a tough, flexible seal that maintains integrity under prolonged exposure to aviation fuels, environmental stress, and thermal cycling, making it a trusted solution for both MRO and OEM operations.
