Abstract: Adhesion-promoting compositions and the use of the adhesion-promoting compositions to provide adhesion-promoting interlayers to enhance adhesion between adjoining layers of sulfur-containing sealants are disclosed. In repair applications, the adhesion-promoting compositions can enhance the adhesion of an overlying radiation-curable sulfur-containing sealant to a damaged or aged sulfur-containing sealant.
