The 3M™ Aerospace AC-730 B-2 Fuselage Sealant from SkyGeek is sold in a pint-size kit and is a high-performance product designed to meet the rigorous demands of the aerospace industry, working in some of the toughest conditions imaginable to ensure a robust and durable fuel system. This sealant is specifically formulated to provide excellent adhesion and sealing properties, making it ideal for use in aircraft manufacturing and maintenance. The AC-730 B-2 sealant is a two-part polysulfide sealant that cures to form a flexible, resilient rubber that resists the effects of weathering, stress and vibration. Its outstanding fuel and chemical resistance makes it suitable for sealing fuel tanks and other critical areas where exposure to harsh substances is expected.

This pint kit includes both the base compound and the curing agent, which are mixed together before application. Because the components are pre-measured, a precise mixture is ensured, resulting in the strongest bond and most reliable hold. The mixed sealant has a working time of two hours, allowing ample time for precise application. Once cured, it forms a durable bond that maintains its integrity over time, even under extreme temperature variations ranging from -65°F to 250°F (-54°C to 121°C). The AC-730 B-2 is also designed for easy application with standard caulking guns or spatulas, ensuring a smooth and efficient sealing process.

Ideal for both new construction and repair work, this sealant offers versatility and reliability for aviation professionals. Its proven performance in demanding environments makes it an essential component for ensuring the safety and longevity of aircraft structures. Whether used in commercial, military, or private aviation applications, the 3M™ Aerospace AC-730 B-2 Fuselage Sealant stands out as a trusted solution for sealing needs in the aerospace sector.
