PPG PR1440A-1/2 (150-ml-Semkit)

Additional Product Information

Overview

PPG PR1440A-1/2 is a two-part polysulfide sealant engineered for sealing integral fuel tanks, fuselage joints, and structural fillets on military and commercial aircraft. Its manganese dioxide-cured formula resists aviation fuels, hydraulic fluids, oils, and extreme temperatures, ensuring structural integrity and safety. The brushable, non-sag consistency allows precise application during both scheduled MRO maintenance and urgent AOG scenarios.
