Royal Adhesives WS-8020RC A1/2 Fuel Tank Sealant (AMS-S-8802 A)

WS-8020RC Class A is two component manganese dioxide cured polysulfide sealant. This product is a low viscosity sealant designed to be brush applied to seal fasteners throughout the aircraft.

The cured sealant has excellent fuel resistance as well as excellent sealing characteristics at temperatures ranging from -65°F (54°C)to 250°F (121°C), including intermittent exposure up to360°F (182°C).WS-8020RC Class A exhibits excellent elastomeric properties and retention after prolonged exposure to jet fuel and aviation gasoline

The uncured product is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature forming a resilient rubber, exhibiting outstanding sealing characteristics.

Key Features:

• Fuel Resistance: Exhibits excellent resistance to jet fuel and aviation gasoline, ensuring durability in demanding aerospace environments.

• Temperature Range: Maintains effective sealing properties across temperatures from -65°F (-54°C) to 250°F (121°C), with intermittent exposure tolerance up to 360°F (182°C).

• Rapid Cure: Formulated for quick curing at room temperature, facilitating efficient maintenance and assembly processes.

• Application: The uncured product is a low-viscosity sealant designed to be brush-applied to seal fasteners throughout the aircraft. It cures at room temperature, forming a resilient rubber with outstanding sealing characteristics.
