PPG PR1770A1/2 SEALANT 100ML 胶水

PR-1770 B类是一种高强度，飞机整体燃料密封胶。

PR-1770 Class B is a high strength, aircraft integral fuel tank sealant.

PPG PR1770使用温度范围从-65°F（-54℃）至250°F（121℃），间歇性偏移高达360°F（182℃）。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。

PPG PR1770 has a service temperature range from -65°F (-54°C) to 250°F(121°C), with intermittent excursions up to 360°F (182°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-1770 B类是由两部分组成的，二氧化锰固化PERMAPOL®P-5聚硫化合物。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使用。对常用飞机基材有着良好的附着力，在室温下固化形成有弹性的密封胶。

PR-1770 Class B is a two-part, manganese dioxide cured Permapol® P-5 polysulfide compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
