PPG PR1782 C2 Low Density Fuel Tank Sealant

The PPG Aerospace® PR-1782 is a two-part, low-density polysulfide fuel tank sealant designed for integral fuel tank sealing and weight-sensitive aerospace applications. Formulated to provide exceptional adhesion, outstanding resistance to aviation fuels, and long-term flexibility, PR-1782 ensures durable performance while reducing overall structural weight.

This advanced sealant is widely specified under Airbus AIMS 04-05-001 / 12 / 14 / 15 standards, making it suitable for both OEM manufacturing and MRO fuel tank maintenance. Its low-density formulation allows operators to achieve weight savings without compromising durability or chemical resistance. Once cured, PR-1782 forms a resilient, flexible seal capable of withstanding aviation fuels, oils, hydraulic fluids, and harsh environmental exposure, ensuring long-term reliability in demanding flight conditions.
