PPG Aerospace sealants have supported aviation maintenance and manufacturing for more than 50 years, with products designed for fuel tanks, windshields, fuselage joints, and electrical applications. PPG offers two-part polysulfide or polythioether systems selected by application area, sealant class, and working life, and many are available in Semkit® cartridges or PRC Pre-mixed and Frozen (PMF) formats for faster, cleaner application. Shop SkyGeek's PPG Aerospace sealants to compare the right option by application, spec, and packaging format.

PPG Aerospace Sealants FAQs
Q: What should I confirm on the product page before ordering?
A: Check the application fit, specification, working life class, package size, and any handling notes on the product data sheet before you buy. That keeps the final selection aligned with the job and the aircraft requirement.
Q: How do I narrow the right sealant when multiple products fit the same application?
A: Use the product page to compare the differences that matter most for the job, then choose the option that matches the required spec, working time, and package format.
Q: How do I know which specification a PPG sealant meets?
A: The applicable aerospace specifications, such as AMS-S-8802 or a PPG or OEM reference, are listed on each product page and data sheet. Always confirm the called-out spec for your aircraft or repair document against the product data sheet before ordering
Q: Which PPG Aerospace sealant is best for corrosion protection?
A: For faying surfaces, fasteners, and joints exposed to moisture, a corrosion-inhibitive sealant is the right family to start with. These formulations combine sealing with active corrosion protection to guard against galvanic and moisture-driven corrosion. For a closer look at how these products work and where to use them, see our PPG Aerospace corrosion-inhibitive sealant product showcase, then compare available options in the category grid above.
Q: What is the difference between Semkit and PMF packaging?
A: Both are designed to speed up application and reduce mixing errors. A Semkit® cartridge holds both parts of the sealant and lets you mix in the cartridge itself, while PRC Pre-mixed and Frozen (PMF) products arrive already mixed and frozen, ready to thaw and apply. Choose the format that best fits your working time, storage setup, and how the sealant will be dispensed on the job.
