Product Information

It is a manganese dioxide cured Permapol P-5 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 up to 20% weight savings per unit volume over traditional sealants used for its purposes. It will also resist limited contact to diphosphate ester based hydraulic fluids.
