特點

Features

這種材料是專為圓角密封和其他飛機機身密封應用。

盡可能多節約30％重量，每單位體積，超過傳統密封較

長期接觸航空噴氣燃料和天然氣后，固化的密封劑仍保持彈性。

會抵制有限接觸二磷酸托架液壓液。

PR-1782 B類是由兩部分組成，二氧化錳固化聚硫密封膠。未固化的材料是一種低弧垂，觸變性膏狀適合配合使用擠壓槍或抹刀。

在室溫下固化，形成有彈性的密封劑，歲常見的飛機基板具有優異的粘附性。

以下測試根據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.
