  • Publication number: 20050224173
    Abstract: A sealing method comprising affixing an adhesive tape (e.g., a pressure-sensitive adhesive tape) to an adherend to be sealed, placing a sealing article that contains a hot-melt/fluidizable thermosetting sealing material on the adhesive tape, and heating the sealing article to a temperature sufficient to allow the article hot-melt/fluidize and thermoset. The adhesive tape has a substrate that suppresses penetration of air trapped in the affixing step between the adherend and adhesive tape into the sealing article.
