Royal Adhesives WS-8032 B2 Low Weight Fuel Tank Sealant AMS3281 TY II

WS-8032 B-2 is an ultra-lightweight, fast-curing, two-component polysulfide sealant designed for aerospace applications, particularly for sealing integral fuel tanks and fuselages. It offers excellent resistance to jet fuel, aviation gasoline, water, alcohols, synthetic oils, and petroleum-based hydraulic fluids.

Key Features and Benefit

• Ultra-Lightweight Composition: Contributes to overall weight reduction in aerospace applications.
• Rapid Curing: Enhances productivity by reducing downtime.
• Temperature Resilience: Performs effectively across a broad temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent exposure up to 360°F (182°C).
• Elastomeric Properties: Maintains flexibility and strength after prolonged exposure to fuels and oils.

Applications:

• Surface Preparation: Clean substrates thoroughly to remove contaminants such as dirt, grease, and processing oils.
• Mixing: Thoroughly mix the two components in the specified ratio (100:12 by weight) until achieving a uniform color and consistency.
• Application: Apply the mixed sealant using an extrusion gun or spatula, ensuring even coverage on the prepared surfaces.
• Curing: Allow the sealant to cure at room temperature. The tack-free time is less than 6 hours, with full cure achieved in under 12 hours.
