PPG Aerospace® PR-1828 B-1/4 White AMS3277J Type 2, Class B-1/4, Grade 1 Spec Rapid Cure Fuel Tank Sealant - 6 oz 654-SemKit

A 6 oz SemKit of PPG Aerospace PRC-Desoto PR-1828 Class B rapid curing, primerless to most common substrates, aircraft integral fuel tank sealant with a 1/4 hour application life. It has a service temperature range from -80°F (-62°C) to 320°F (160°C), with intermittent excursions up to 420°F (216°C). This material is designed for fillet sealing of 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-1828 Class B is a two-part, epoxy cured Permapol® P-3 polythioether compound. The uncured material is a low sag, thixotropic paste, suitable for application by extrusion gun or spatula. Unlike standard polysulfide fuel tank sealants, it can cure at low temperatures and is unaffected by changes in relative humidity. This sealant has excellent adhesion to common aircraft substrates.
