本规范涵盖双组分可刷或可喷涂液体形式的纤维增强树脂复合结构用氟碳（FKM）弹性涂层材料。这些产品通常用于保护飞机和导弹天线罩及其他部件免受雨水侵蚀、空气动力加热、降水静电积聚、热闪光暴露和风化，但使用不限于此类应用。

This specification covers fluorocarbon (FKM) elastomeric coating materials for fiber-reinforced-resin composite structures in the form of two-component brushable or sprayable liquids.These products have been used typically for protection of aircraft and missile radomes and other components from rain erosion, aerodynamic heating, precipitation static build-up, thermal flash exposure, and weathering, but usage is not limited to such applications.
