This product is a manganese dioxide cured polysulphide 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 -54°C (-65°F) to 121°C (250°F), with intermittent excursions up to 135°C (275°F).
The sealant cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates. The cured sealant maintains elastomeric properties after exposure to both jet fuel and aviation gas.
