What Are the Applications and Features of PRC Desoto Sealants?

Aviation sealants block the passage of fluids through the surface, joints, or openings in an aircraft's fuel tanks, access doors, windshields, and other components.  Aerospace sealants are meant to prevent fluid leaks, air leakage, corrosion and oxidation, water or dust intrusion, and the spread of fire or flame. They're vital for aircraft safety and operation.

PPG Aerospace – PRC-DeSoto Aerospace Sealants

One of the most popular and reliable brands of aerospace sealants is put out by a company called PPG under the name PRC DeSoto Sealant. PRC DeSoto Sealants are used by some of the aerospace industry's leading manufacturers, including Boeing, Raytheon, Airbus, Sikorsky, Lockheed, and others.

For more than 50 years, PPG Aerospace – PRC-DeSoto has been a leader in developing a wide range of products essential to aerospace manufacturing, maintenance, and repair, including PRC® aerospace sealants. These were the first elastomeric sealing products capable of resisting deterioration from long-term exposure to jet fuel.
