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 from -54°C (-65°F) to 121°C (250°F), with short term recurring exposures (approximately 6 hours) to 182°C (360°F). It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
