It is a manganese dioxide cured Permapol P-5 polysulfide compound and the uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It has a service temperature range of -55°C (-67°F) to 180°C (356°F).
The sealant cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates. Cured sealant maintains elastomeric properties after exposure to both jet fuel and aviation gas.
