PR-2001 B類是一種快速固化，低氣味，飛機整體油箱密封膠。

PR-2001 Class B is a rapid cure, low odor, aircraft integral fuel tank sealant.

工作溫度范圍從-54°C（-65°F）到150°C（300°F），與間歇偏移到216°C（420°F）。這種材料是專為圓角密封油箱和其他飛機機身密封應用。

It has a service temperature range from -54°C (-65°F) to 150°C (300°F), with intermittent excursions up to 216°C (420°F). This material is designed for fillet sealing of fuel tanks and other aircraft fuselage sealing applications.

特點

Features

經過長時間的暴露在航空噴氣燃料和天然氣下，固化密封膠保持良好的彈性性質。

PR-2001 B類是由兩部分組成，環氧樹脂固化PERMAPOL?P-3.1硫醚化合物。

未固化的材料是一種低凹陷，觸變膏，適合于應用通過擠壓槍或抹刀。

不同于標準的多硫化物油箱密封劑，它在低溫下固化，并不受相對濕度變化的影響。

對常見的飛機基板具有優異的粘附性。

The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. PR-2001 Class B is a two-part, epoxy cured Permapol? P-3.1 polythioether compound.

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

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

This sealant has excellent adhesion to common aircraft substrates.
