Royal Adhesives WS-8035 B2  Low Weight Fuel Tank Sealant BMS5-184

WS-8035 B2 is a rapid-cure, lightweight, two-component polysulfide sealant specifically formulated for aerospace applications, particularly for sealing integral fuel tanks and fuselages. Its advanced formulation offers high-temperature resistance and durability, ensuring reliable performance in demanding environments

Key Features and Benefits

• Lightweight Composition: Contributes to overall weight reduction in aerospace applications.
• Rapid Curing: Enhances productivity by reducing downtime.
• High-Temperature Resistance: Ensures durability and reliability in fuel tank and fuselage applications.
• Enhanced Performance: Maintains robust performance standards while delivering a faster build, lighter weight, and lower material costs compared to traditional sealants.

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.
