PPG PR1750A2 150ML SEMKIT 胶水

PR-1750 A级飞机整体燃料密封胶。

PR-1750 Class A is an aircraft integral fuel tank sealant.

工作温度范围从-65°F（-54C）到250°F（121℃），间歇性偏移高达360°F（182℃下）。这种材料是专为刷密封油箱和其他飞机机身密封应用的紧固件。

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-1750 A类是由两部分组成，二氧化锰固化多硫化物。未固化的材料是适合应配用刷的厚度可达25密耳。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。

It has a service temperature range from -65°F (-54C) to 250°F (121°C), with intermittent excursions up to 360°F (182°C). This material is designed for brush Sealing of fasteners in 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-1750 Class A is a two-part, manganese dioxide cured polysulfide compound. The uncured material is suitable for application by brush in thickness up to 25 mils. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
