    摘要: An article adapted for sealing a discontinuity in a surface. The article includes a melt-flowable composition that flows and seals the discontinuity when the article is heated to a sufficient temperature and a polymeric cap controlling the melt-flow behavior of the melt-flowable composition to substantially confine the melt-flowable composition to the area underneath the cap, when the article is heated to a temperature sufficient to cause the melt-flowable composition to flow, and then cooled.

    摘要: The present invention includes a method for sealing a discontinuity in the surface of a substrate comprises the steps of: (a) placing over the discontinuity an article comprising (i) a melt-flowable composition characterized by a first width, and (ii) a shaped, polymeric cap having a pre-selected, cross-sectional profile characterized by a second width and a shape in which the thickness of the cup across its width, the width of the cap, or both the width and thickness of the cap vary; (b) heating the article to cause the melt-flowable composition to flow and seal the discontinuity, where the cap controls the melt-flow behavior of the melt-flowable composition to substantially confine the melt-flowable composition to the area underneath the cap; and (c) allowing the article to cool while substantially retaining the pre-selected cross-sectional profile of the cap. The present invention also includes various articles for use in the method. The article and the method are particularly useful for sealing the joint in a motor vehicle roof ditch.

    摘要: A multi-layer article which may be provided in the form of a tape comprises a conformable, compressible, melt flow-resistant core layer having first and second major surfaces, a sealant layer on the first major surface of the core layer, and optionally a bonding layer on the second major surface of the core layer. The sealant layer and the bonding layer each have a surface available for contacting a separate substrate. Various thermoset and foam core layers are disclosed as are thermosettable and thermoplastic sealant layers. The articles are useful for sealing two substrates together, particularly where one of the substrates is glass. Thus, the articles are especially adapted for sealing motor vehicle windshields to a frame. Various assemblies and methods for producing the same are also described.
