We studied polyurethane coating aging and determined polyurethane coating/polysulfide sealant interfacial integrity using scanning electron microscopy. A rapid microspecimen hand-pulled peel test was developed that will find application in designing future aircraft sealants. Dynamic mechanical analysis was used to follow polyurethane aging.
