PR-1826 Class B is a rapid cure, aircraft integral fuel tank sealant.

特點

Features

使用溫度范圍從-80°F（-62°C）到320°F（160℃），間歇性偏移到420°F（216°C）。

這種材料是專為圓角密封油箱和其他飛機機身密封應用。

長期接觸航空噴氣燃料和天然氣后，固化的密封劑仍保持彈性。

未固化的材料是一種低凹陷，觸變膏，適合于應用程序通過擠壓槍或抹刀。與標準多硫化物油箱密封劑，它可以在低溫下固化，不受相對濕度的變化影響。

對常見航空基板有著優異的附著力。

 It has a service temperature range from -80°F (-62°C) to 320°F (160°C), with intermittent excursions up to 420°F (216°C).

This material is designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications.

The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas.

The uncured material is a low sag, thixotropic paste, suitable for application by extrusion gun or spatula.

Unlike standard polysulfide fuel tank sealants, it can cure at low temperatures and is unaffected by changes in relative humidity.

This sealant has excellent adhesion to common aircraft substrates when correctly primed with PR-1826 Adhesion Promoter.
