Each of our aerospace sealants has also been specially developed to protect your aircraft from different types of wear and tear. If corrosion is your main concern, we carry corrosion inhibitive sealants that guard your plane from corrosive substances like H20, fuel, aircraft chemicals and more. You can also opt for firewall sealant, which keeps your plane safe in the event of extreme high temperature. Solvent-resistant sealant is made to neutralize the effects of chemical-based solvents. We also carry repair sealants for making small repairs to your aircraft and electrical sealant, which is made to be used with sensitive electronics and electrical metals.

When applying aircraft sealant to your airplane, you may need other products in order to maintain, remove or increase the lifespan of your sealant. Don't worry - we carry those too. In fact, we carry an entire line of specialty products that are made to be used in conjunction with aviation sealant. Start off with a high-quality sealant primer and sealant adhesion promoter, which will help get the surface ready and increase the adhesion between sealants and metal surfaces. Reduce the amount of time it takes to treat your aircraft with the use of a sealant cure accelerator, which speeds up curing times so you can get back in the skies sooner. Sealant cleaning wipes provide a safe way to clean your sealant-treated aircraft while sealant removers will help you take off unwanted coatings.

Frequently Asked Questions

Q: What is aerospace sealant?

A: Aerospace sealant is a special type of flexible material used in the aviation industry to create airtight and watertight seals on aircraft components. Aircraft sealant is typically formulated to withstand extreme conditions, like high temperatures, high pressures, vibration and exposure to all kinds of chemicals, including aviation fuel and gasoline.

Q: What types of aviation sealants does SkyGeek offer for sealing fuel tanks?

A: When sealing fuel tanks, you typically need class B or C sealant to achieve a fillet seal or a fay seal. For fillet sealing, SkyGeek offers class B sealant, which has a thicker consistency that's ideal for fillet sealing. For fay sealing, we recommend using class C sealant. Class C sealant is thinner than class B sealant, making it ideal for fay sealing. All aerospace sealants are formulated for specific purposes and environments.

Q: What are the classifications of aircraft sealants?

A: Sealants for aircraft can grouped into three classes: A, B and C. Some say there is also an S class, which indicates a spray sealant. Class A sealant is designed for brush application. Class B sealant has a thicker consistency and is used for fillet sealing. Class C sealant is thinner than class B and is used for fay sealing. The class you choose will depend on your needs and how you plan to use the sealant. Class B and Class C sealants are most often used for fuel tanks.

Q: How does SkyGeek's selection of fuel-resistant and high-temperature sealants help protect different parts of an aircraft?

A: Fuel-resistant and high-temperature sealants help protect critical aircraft components by preventing leaks and guarding against corrosion. Fuel tank sealer or fuel tank sealant is designed for use in the fuel system, while high-temperature sealants are better for areas exposed to heat, like around the landing gear. These sealants are designed to withstand harsh environmental conditions, exposure to chemicals and extreme temperatures while providing a strong, reliable seal. They are also designed to maintain some flexibility after curing, ensuring that they remain bonded when exposed to vibrational forces. When used correctly, choosing a fuel-resistant and high-temperature sealant will ensure the integrity of fuel tanks, engine compartments and airframe parts, maintaining safety and ensuring reliable performance.
