PR-1772 Class B is a lightweight sealant. It has a service temperature range from -65°F (-54°C) to 250°F (121°C) with intermittent excursions up to 135°C (275°F). It provides thirty percent weight savings per unit volume compared to conventional sealants used for these purposes. Cured sealant retains excellent elastomeric properties after limited exposure to both jet fuel and aviation gasoline (avgas).
PR-1772 Class B is a two part, chemically curing polysulfide compound. Uncured material is a low sag, thixotropic putty suitable for application by extrusion gun or spatula. It cures at room temperature to form a flexible sealant with excellent adhesion to common aircraft surfaces.
