Features

• High Hydrocarbon Resistance: Retains flexibility and bond strength after prolonged immersion in jet fuels, avgas, water, and synthetic oils.

• Convenient 2-Hour Application Life: Class B-2 thixotropic paste consistency allows a manageable 2-hour working time for easy application via extrusion gun or spatula.

• Severe Temperature Stability: Maintains a reliable seal across continuous operating temperatures from -65°F to 250°F (-54°C to 121°C), with intermittent peaks up to 275°F (135°C).

• Broad Military Specification Approval: Meets stringent aerospace standards including AMS-S-8802 Type 2 Class B-2.

Fuel leaks or failed fuselage seals present serious structural hazards and compromise operational safety. Using substandard sealants risks poor adhesion, swelling, or cracking under constant contact with aggressive jet fuels and extreme thermal cycling. PPG Aerospace P/S 890 B-2 provides aircraft mechanics and maintenance teams with full peace of mind, ensuring low-sag application and a high-integrity barrier that stands up to demanding flight conditions.
