Royal Adhesives WS-8020RC B-6 Fuel Tank Sealant (AMS3276)

WS-8030 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

• • Lightweight Composition: Contributes to overall weight reduction in aerospace applications.
  • Fuel Resistance: Provides excellent resistance to jet fuel and aviation gasoline.
  • Fluid Compatibility: Demonstrates strong resistance to water and alcohols.

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 (100:10 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 approximately 2 hours, with full cure achieved in about 8 hours.
