Royal Adhesives WS-8020RC B2 Fuel Tank & Fuselage Sealant (AMS-S-8802 B / AMS3276 / CMNP021 )

The WS-8020RC B2 is a rapid-cure, two-component polysulfide sealant designed for integral fuel tanks and other aerospace applications. It offers excellent resistance to jet fuel, aviation gasoline, water, alcohols, synthetic oils, and petroleum-based hydraulic fluids. The cured sealant maintains its elastomeric properties across a temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent exposure up to 360°F (182°C).

Key Features and Benefits:

• Rapid Cure: Enhances productivity by reducing curing time.
• Fuel and Chemical Resistance: Withstands prolonged exposure to various fuels and fluids.
• Temperature Resilience: Performs effectively across a broad temperature spectrum.
• Thixotropic Paste: Low-sag consistency suitable for application by extrusion gun or spatula.
• Excellent Adhesion: Bonds well to metals, composites, primers, and coatings used in modern aircraft.

Applications:

• Surface Preparation: Clean substrates with appropriate solutions to remove contaminants.
• Mixing: Combine components thoroughly following the specified ratio.
• Application: Apply using an extrusion gun or spatula.
• Curing: Allow to cure at room temperature; curing times may vary based on environmental conditions.
