PPG AEROSPACE PR1422 B-2 BROWN AMS-S-8802D TYPE 1, CLASS B-2 SPEC FUEL TANK SEALANT - PINT KIT

The PPG Aerospace® PR1422 B-2 Brown AMS-S-8802D Type 1, Class B-2 Spec Fuel Tank Sealant – Pint Kit is a high-performance two-part manganese-dioxide-cured polysulfide compound engineered for demanding aerospace fuel containment systems. With a service temperature range from –65 °F (–54 °C) up to 250 °F (121 °C) and intermittent excursions to 275 °F (135 °C), it offers exceptional low-temperature flexibility, no cracking or adhesion loss at –54 °C, and long-term elastomeric resilience after prolonged immersion in jet fuel or aviation gasoline. It exhibits excellent adhesion and peel strength on anodized aluminum, Alodine-treated aluminum, titanium alloy and stainless steel substrates, maintains integrity under pressure and vibration, resists aviation fuels, oils, hydraulic fluids and salt-water environments, and is equally suited for OEM assembly and MRO fuel-tank repair operations where reliable structural sealing and durability are essential
