特点

Features

这种材料是专为圆角密封和其他飞机机身密封应用。

尽可能多节约30％重量，每单位体积，超过传统密封较

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。

会抵制有限接触二磷酸托架液压液。

PR-1782 B类是由两部分组成，二氧化锰固化聚硫密封胶。未固化的材料是一种低弧垂，触变性膏状适合配合使用挤压枪或抹刀。

在室温下固化，形成有弹性的密封剂，岁常见的飞机基板具有优异的粘附性。

以下测试根据AIMS -04-05-012和AIMS -04-05-001。

This material is designed for fillet sealing and other aircraft fuselage sealing applications.

It offers as much as a thrity percent weight savings, per unit volume, over traditional sealants used for these purposes.

The cured sealant maintains excellent elastomeric properties after prolonged exposure to aircraft fuels both jet fuel and aviation gas, and will resist limited contact to diphosphate ester based hydraulic fluids.

PR-1782 Class B is a two-part, manganese dioxide cured polysulfide sealant. 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.

The following tests are in accordance with AIMS -04-05-012 and AIMS -04-05-001.
