PPG AEROSPACE® Integral Fuel Tank Sealants SKU: PPG-SLNT-FLTNK

For more than 50 years, PPG AEROSPACE® – PRC-DeSoto® has been a leader in the development of products fundamental to aerospace manufacturing, maintenance, and repair. The company manufactures and provides a unique group of products including aircraft windshields and windows to the commercial, regional, military and general aviation segments as well as aircraft primers, coatings and sealants for aircraft structures used in aviation and milirary applications. In addition, high performance Industrial Adhesives and Sealants  are also offered to provide protection from fuel and petroleum exposure as well as sealants for Telecom and Utility applications.

PPG AEROSPACE® – PRC-DeSoto® products are offered in different classes, specifications, application times and convenient container options including SEMCO Semkit® packages containing both the base and accelerator in one pack.

3 classes are generally used for the classification of sealants (A, B and C) although an S class does apply in some cases where a sealant can be sprayed.

Class A – Brush application, generally used on fasteners

Class B – Thicker consistency, used for fillet and injection seals

Class C – Thinner than Class B, used for fay sealing

Application times are expressed in hours (2 indicating 2 hours 1/2 indicating half an hour).

PPG AEROSPACE® integral fuel tank sealants for aerospace applications are high-performance products designed to provide long-lasting protection and sealing for aircraft fuel tanks. These sealants, such as the PR-1422 and Pro-Seal 890 were the first fully jet fuel resistant sealants. They offer excellent adhesion, flexibility, and resistance to fuels, oils, and other chemicals. They ensure leak-proof integrity under various temperature and pressure conditions, contributing to the overall safety and efficiency of aircraft operations. 

PPG’s Aircraft Fuel Tank Sealants are included in this presentation while respective Aircraft Fuselage, Firewall Sealants and Corrosion Inhibitive Sealants and Coatings are separately presented.

PPG AEROSPACE®  Integral Fuel Tank Sealants

PPG AEROSPACE® manufactures an extensive range of Integral Fuel Tank Sealants some of which are briefly presented below. They are available in different packings.

PPG PR-1422 (A and B  Classes) / PR-1440 (A, B, and C Classes) Integral Fuel Tank Sealants

PR-1422 Class B is an aircraft integral fuel tank sealant. It has a service range from -65F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). This material is designed for fillet sealing fuel tanks and other aircraft fuselage sealing applications. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. PR-1422 Class B is a two-part, dichromate cured poly-sulfide compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form resilient sealant having excellent adhesion to common aircraft substrates.

Due to REACH regulations of the European Union  (Registration, Evaluation, Authorization, and restriction of Chemical substances), production and supply of this product in the European Union is ceased. Production in the United States and availability of the product to the America’s , Africa, the Middle East, and Asia/Pacific is unaffected.

The replacement products for all grades of PPG PR-1422, are PPG PR-1440 Class A or B aircraft integral fuel tank sealants with a service temperature range from -54°C (-65°F) to 121°C (250°F), with intermittent excursions up to 135°C (275°F). The cured sealants maintain excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. The PPG PR-1440 Class A is designed for brush sealing of fasteners in fuel tanks and other aircraft fuselage sealing applications. The PPG PR-1440 Class B is designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications.

PPG PR-1750 (A and B  Classes) Integral Fuel Tank Sealants

PR-1750 integral fuel tank sealant is a two-part, manganese dioxide cured polysulfide compound with a service temperature range form -65°F (-54°C) to 250°F (121°C), and intermittent excursions up to 360°F (182°C). PR1750 Class A sealant is designed for brush sealing of fasteners in fuel tanks and other aircraft fuselage sealing applications while PR1750 Class B sealant for fillet sealing of fuel tanks and other aircraft fuselage sealing applications. The cured sealant maintains excellent elastomeric properties after exposure to both jet fuel and aviation gas.

PR-1776M Class B Low Weight Integral Fuel Tank Sealant

PR-1776MB Class B is a low density, high temperature aircraft integral fuel tank sealant with a service temperature range from -65°F (-54°C) to 250°F (121°C), with very limited excursions up to 360°F (182°C). Recommended for use on Boeing and Bombardier aircraft. This material is designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications. It offers as much as a twenty percent weight savings, per unit volume, over traditional sealants used for these purposes. The cured sealant maintains excellent elastomeric properties after prolonged exposure to aircraft fuels both jet fuel and aviation gas, and will resist limited contact to diposphate ester based hydraulic fluids.

PPG PR-1782 Multipurpose Aerospace Sealant (A, B, and C Classes)

The PR-1782 is the first lightweight low density, multipurpose aerospace sealant for sealing both fuel tank and fuselage. Listed under PPG AEROSPACE®  Fuselage Sealants.
