The Significance of Processing Variables on the Adhesion of Sealants and Organic Coatings to Metallic Aircraft Surfaces

Abstract

This report describes the results obtained in a study program to improve adhesion between aircraft-type metals and organic coatings currently used. Metals studies included aluminum 7075 and 2024 alloys, titanium Ti6A14V, steel 4340 and cadmium- plated steel 4340. The metals were treated with various surface treatments. The coating materials studied were epoxy polyamide primer, polyurethane enamel, acrylic nitrocellulose laquer, polysulfide sealant, neoprene rain erosion coating and polyurethane elastomer. The Blister Test Method was used in evaluating adhesion.
