Top Brand Aerospace Sealants for Aircraft Maintenance and Repair

Apply sealant, remove sealant, repeat.  BAC stocks PPG and Flamemaster aircraft sealant, as well as the tools you need to get the job done.  We carry battery-powered, pneumatic and manual sealant guns for application and scrapers and cutters for removal.  

Aircraft sealants are essential materials used to prevent leaks, protect structural integrity, and enhance the durability of aircraft. The primary types of sealants include polysulfide, silicone, polyurethane, and fluorosilicone, each offering unique properties tailored to specific applications. Polysulfide sealants, known for their flexibility and resistance to fuels and oils, are commonly used for fuel tanks and other fuel-related components. Silicone sealants provide excellent temperature resistance and are often employed in high-temperature areas such as engine components. Polyurethane sealants are valued for their strength and durability, making them suitable for various structural applications. Fluorosilicone sealants, offering resistance to both fuels and extreme temperatures, are typically used in demanding aerospace environments. Application methods vary depending on the sealant type and the area of use. Common methods include hand application with a spatula or caulking gun, automated dispensing systems for precision, and pressure pot systems for larger-scale applications. Proper surface preparation, including cleaning and priming, is critical to ensure optimal adhesion and performance of the sealant.
