PR-2001 B类是一种快速固化，低气味，飞机整体油箱密封胶。

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

工作温度范围从-54°C（-65°F）到150°C（300°F），与间歇偏移到216°C（420°F）。这种材料是专为圆角密封油箱和其他飞机机身密封应用。

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.

特点

Features

经过长时间的暴露在航空喷气燃料和天然气下，固化密封胶保持良好的弹性性质。

PR-2001 B类是由两部分组成，环氧树脂固化PERMAPOL®P-3.1硫醚化合物。

未固化的材料是一种低凹陷，触变膏，适合于应用通过挤压枪或抹刀。

不同于标准的多硫化物油箱密封剂，它在低温下固化，并不受相对湿度变化的影响。

对常见的飞机基板具有优异的粘附性。

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.
