Royal Adhesives WS-8040 B-2 Windshield Sealant - Non-Chromate

WS-8040 B-2 is a non-chromate, two-component polysulfide sealant specifically formulated for aerospace applications, particularly for sealing windshields. Its advanced formulation offers high-temperature resistance and durability, ensuring reliable performance in demanding environments.

Key Features and Benefits

• Non-Chromate Composition: Provides corrosion protection without the use of chromates.
• Rapid Curing: Enhances productivity by reducing downtime.
• High-Temperature Resistance: Ensures durability and reliability in windshield applications.
• Enhanced Performance: Maintains robust performance standards while delivering a faster build, lighter weight, and lower material costs compared to traditional sealants.

Applications:

• 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.
