Royal Adhesives WS-8032 B1/2 Low Weight Fuel Tank Sealant AMS3281 TY II

WS-8032 Class BLow Weight Fuel Tank Sealant WS-8032 is a two component light weight manganese dioxide cured polysulfide sealant designed to meet the requirements of AMS 3281 fuel tank specifications. It has outstanding adhesion to the common aerospace substrates as well as excellent sealing characteristics at temperatures ranging from -65F (54C) to 250F (121C), including intermittent exposure up to 360F (182C).WS-8030 Class B exhibits excellent elastomeric properties and retention after prolonged exposure to jet fuel and aviation gasoline.

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.
    • 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 4 hours, with full cure achieved in under 6 hours.
