PPG-PRC Desoto Aircraft Sealants

While BAC stocks the most popular PRC sealants and sizes, some sealants listed are special order only due to low demand and limited shelf life.  Special order sealants typically have a 3-6 week lead time.   If you do not see your sealant listed, please call us at 888-239-6625. 

Two-part aircraft sealants by PPG (formerly PRC-Desoto) are high-performance materials designed to provide exceptional sealing and protection for aerospace applications. These sealants consist of a base compound and a curing agent that, when mixed, form a durable and flexible seal capable of withstanding extreme temperatures, pressures, and environmental conditions. Renowned for their superior adhesion to various substrates, including aluminum, composites, and titanium, aircraft sealants are widely used in fuel tanks, fuselage assembly, and other critical areas where reliability is paramount. They offer excellent resistance to chemicals, including aviation fuels and hydraulic fluids, ensuring long-term performance and compliance with stringent aerospace standards.
