Abstract

<strong>Form.</strong> <br>This specification establishes the requirements for coating systems having high durability to be used in finishing aircraft exterior surfaces. These coating systems normally are comprised of a surface treatment, a primer, and a topcoat and include a chemical stripper and a cleaning compound for topcoat washing. <br><strong>Application.</strong> <br>Systems are qualified for use on external surfaces of military aircraft but are not limited to such application. If the coating systems qualified to this specification are to be used on other than external surfaces, further testing will be required for the specific application. <br><strong>Classification.</strong> <br>The systems under this specification consist of the following types, classes, and grades. <br>Type 1: Coating system containing chromium compounds. <br>Type 2: Coating system, chromium free. <br>Class 1: Standard Flexibility Coating System <br>Class 2: High Flexibility Coating System <br>Grade 1: Standard Pigmented Coating System <br>Grade 2: Low IR Pigmented Coating System <br><strong>Colors.</strong> <br>Coating systems should be furnished in all colors and gloss ranges as designated in the current issue of FED-STD-595. Colors not in FED-STD-595 should be furnished as specified by the procuring activity. <br><strong>Safety-hazardous materials.</strong> <br>While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe, proper use and disposal of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved. <b><u>Intended Use:</u></b> The coating/finish system covered by this specification is intended for use on external moldlines of military aerospace weapon systems. In general, the components comprising the coating system work in concert to provide superior weather and chemical resistance with protection against corrosion and may be used in applications other than aerospace weapon systems. Additional testing would be needed to address the specific requirements of other applications. This specification contains military specific camouflage gloss requirements, gunship gloss requirements, and low IR requirements. <br>
