PR-1826 B类是一种快速固化，飞机整体燃料密封胶。

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

特点

Features

使用温度范围从-80°F（-62°C）到320°F（160℃），间歇性偏移到420°F（216°C）。

这种材料是专为圆角密封油箱和其他飞机机身密封应用。

长期接触航空喷气燃料和天然气后，固化的密封剂仍保持弹性。

PR-1826 B类是由两部分组成，环氧树脂固化PERMAPOL®P-3硫醚化合物。

未固化的材料是一种低凹陷，触变膏，适合通过挤压枪或抹刀应用。

不像标准的聚硫燃料密封剂，它可以在低温下固化，不受相对湿度变化的影响。

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.

PR-1826 Class B is a two-part, epoxy cured Permapol® P-3 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 can cure at low temperatures and is unaffected by changes in relative humidity.
