Royal Adhesives WS-8032S B2 Low Weight Fuel Tank Sealant BAMS 552-008 / BAMS 552-009

WS-8032S B-2 is an ultra-lightweight, fast-curing, two-component polysulfide sealant specifically formulated for aerospace applications, such as 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 Benefits

• 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.
• Non-Chromate Corrosion Inhibition: Provides corrosion protection without the use of chromates.

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.
