Product Information
This product acts as an effective barrier against the common causes of corrosion on aluminum alloys or between dissimilar metals. It has a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates. The cured sealant maintains elastomeric properties after limited exposure to both jet fuel and aviation gas.
