Analysis of the NAVAIRDEVCEN (Naval Air Development Center) Self-Priming Topcoat on Graphite/Epoxy Composites

摘要

The standard coating system for Navy aircraft consists of an epoxy- polymade primer (MIL-P-2337) under a polyurethane topcoat (MIL-C-83286). In September of 1986, the Naval Air Development Center developed a self-priming (single coating) to replace the standard Navy aircraft coating system. Equivalent or superior paint properties were achieved with potential material and labor savings. This self-priming topcoat was developed for use on aluminum-skinned aircraft. Since the amount of polymeric composite components used on naval aircraft is rapidly increasing, the current effort was undertaken to determine the compatibility of the self-priming topcoat with graphite/epoxy composite substrates.
