article. ### Claim 15 (depends on 13) The article of claim 13, wherein the article comprises an opening, seam, or space, and the self-curing sealant composition is disposed in the opening, seam, or space in a manner that is effective to fill the opening, seam, or space. ### Claim 16 A method comprising applying a self-curing sealant composition to at least one location under conditions effective to cause the self-curing sealant composition to form a connecting bond between two or more objects, articles or bodies or to fill at least a portion of an opening, junction or other space in, on or between one or more objects, articles or bodies, wherein the self-curing sealant composition comprises: at least one polymer selected from acrylic polymers, polyurethanes or polyureas, and
