AMS-STD-32239 Coating System, Advanced Performance, for Exterior Aerospace Applications

This specification establishes requirements for coating systems having high durability for use as aircraft exterior surface finishes. These coating systems normally are comprised of a surface treatment, a primer, and a topcoat. Alternatively, a coating system may be comprised of a surface treatment and a unicoat. Testing includes use of a chemical stripper for removal and a cleaning compound for topcoat washing, but these components are not a part of the coating system.
