Royal Adhesives WS-8033 B1/2 Ultra light Weight Fuel Tank Sealant MEP 09-084

WS-8033 B-1/2 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 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 3 hours, with full cure to 30A hardness achieved in under 4 hours.
