Overview
Boeing provides PPG Aerospace/PRC DeSoto PR1828B1-2, PR-1828 Class B as a rapid curing aircraft integral fuel tank sealant. 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 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.
Features & Benefits
Low-temperature flexibility at -65°C (-85°F) with no cracking, checking, or loss of adhesion
Excellent repairability to both freshly cured sealant and fuel-aged abraded fillets
Fungal resistance and non-nutrient properties
