Investigation of Coating Systems and Removers for Graphite/Epoxy Composite Surfaces.

Abstract

Permanent primer coating systems and strippable coating systems were investigated for use on both graphite/epoxy composite and aluminum surfaces. While the so-called permanent primer systems did not exhibit sufficient chemical resistance to be useful, two strippable systems were identified. One coating system, based on a nitrocellulose lacquer release coat, was suitable for graphite/epoxy surfaces but not aluminum. A compatible chemical remover was developed for this system using methylene chloride as the solvent base. The second strippable system, based on a polysulfide release coat, can be used on both surfaces and requires a polysulfide remover. Two methods were developed to determine compatibility of chemical removers with graphite/epoxy composites.
