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.

[ What is claimed is:] [1.]1. An article comprising (a) a conformable, compressible, melt flow-resistant core layer having first and second major surfaces, and (b) a thermosettable sealant layer on said first major surface of said core layer, wherein said thermosettable sealant layer, upon curing, is not aggressively and permanently tacky at room temperature and can not firmly adhere to a wide variety of dissimilar surfaces upon mere contact and more than hand or finger pressure,said sealant layer having a surface available for contacting a substrate, and said core layer has an ultimate tensile strength no greater than the ultimate tensile strength of said thermosettable sealant layer.
