Sealant composition, article including same, and method of using same

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.
