PR-1776M Class B is a manganese dioxide cured, Permapol P-5 modified polysulfide compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula.
It has a service temperature range of -54°C (-65°F) to 121°C (250°F) with intermittent excursions up to 182°C (360°F). It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
This product offers approximately 20% weight savings per unit volume over traditional sealants used for these purposes. It also resists limited contact with diphosphate ester-based hydraulic fluids.
