Product Review:
The 3M™ Aerospace AC-350 B1/2 Quick Cure Fuel Tank Fuselage Sealant from SkyGeek is the smart choice for stopping leaks before they can stop you. The high-quality fuel tank and fuselage sealant is designed for aviation applications and is designed to maintain flexibility even after curing. This 3.5-ounce cartridge of sealant is renowned for its superior resistance to aviation gasoline and jet fuel, as well as chemicals and petroleum products. It is a two-part polysulfide sealant that cures at room temperature to a flexible, resilient rubber with excellent adhesion to aluminum, magnesium, titanium, steel and other surfaces.
The AC-350 B1/2 sealant offers impressive performance in terms of durability and reliability. It has a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). This makes it ideal for use in a wide range of conditions and environments. The application process is straightforward and the cure time is relatively quick, making it convenient for users.
Top Three Reasons for Interest:
- High Resistance: The AC Tech AC-350 B1/2 sealant offers outstanding resistance to aviation fuels, chemicals, and petroleum products. This makes it an excellent choice for customers seeking a reliable solution for sealing fuel tanks and fuselages.
- Wide Service Temperature Range: With a service temperature range from -65°F to 250°F, this sealant can withstand extreme conditions without failing. This feature would appeal to customers who operate in varying climates or harsh weather conditions.
- Easy Application and Quick Cure Time: The sealant is easy to apply and cures quickly at room temperature, forming a strong bond without the need for chemical activators or supplemental heat. This would be attractive to customers who value convenience and efficiency in their maintenance tasks.

*Application life refers to the length of time that mixed compound remains at a consistency suitable for application with spatula or caulking gun. Application life is always measured at a standard temperature of 77 degrees F with a relative humidity of 50%. In general, for every 20 degree rise in temperature, the application life is halved; and for every 20 degree drop, it is doubled. High humidity levels during the mixing process will shorten application life.
**Tack-free time is the length of time after which a mixed sealant will no longer tightly adhere to LP-P-690 standard low-density polyethylene film.
***Cure time is defined as the length of time it takes AC-350 Class B sealant to reach 30A hardness. It depends on three factors: remaining application life, temperature and relative humidity. The temperature/humidity factors for application life also apply to curing. To accelerate the curing process, apply heat up to (but no more than) 140 degrees F.
