- Description: PR-1422 B-1/2 Brown PRC Standard Spec Fuel Tank Sealant
- Availability: Send RFQ
PPG PR1422 Class B is an aircraft integral fuel tank sealant with a service temperature range from -65°F (-54°C) to 250°F (121°C), and intermittent excursions up to 275°F (135°C). This material is designed for fillet sealing of fuel tanks and other air-craft fuselage sealing applications. The cured sealant maintains excellent elastomeric properties after pro-longed 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 lowsag, thixotropic paste suitable for application by
extrusion gun or spatula. It cures at room tempera-
ture to form a resilient sealant having excellent adhe-
sion to common aircraft substrates.
