Overview
The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. Unlike standard polysulfide fuel tank sealants, it can cure at low temperatures and is unaffected by changes in relative humidity. 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 sealant has excellent adhesion to common aircraft substrates when correctly primed with PR-1826AP Adhesion Promoter. The storage life of PR-1826 Class B is at least 9 months when stored at temperatures between 60°F (16°C) and 80°F (27°C) in original, unopened containers.
