Overview
The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. The uncured material is a roller grade liquid suitable for application by brush, extrusion gun, or spatula. It cures at room temperature to form a resilient sealant with excellent adhesion to common aircraft substrates. The service temperature range is from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). The storage life of P/S 890 Class C is at least 9 months when stored at temperatures below 80°F (27°C) in original, unopened containers. C-24 represents an application life of 24 hours.
