Abstract: Curable and cured compositions as well as articles containing the curable or cured compositions are provided. The cured compositions are typically a semi-structural or structural adhesive. Advantageously, the cured compositions can be removed (e.g., de-bonded) from the various surfaces of the articles after the useful lifetime of the articles, to correct misplacement of a part during manufacturing, or to repair the electronic device. The separation step occurs using a direct current electric potential across the cured composition.

Abstract: The double-sided pressure-sensitive adhesive tape includes a tissue support having a first face and a second face, a first pressure-sensitive adhesive disposed on the first face of the tissue support, and a second pressure-sensitive adhesive disposed on the second face of the tissue support. The first pressure-sensitive adhesive and the second pressure-sensitive adhesive are each crosslinked acrylic-based pressure-sensitive adhesives that are the same or different from each other, and the tissue support is impregnated by the first pressure-sensitive adhesive and the second pressure-sensitive adhesive. The article includes a first substrate and the double-sided pressure-sensitive adhesive tape, in which the first pressure-sensitive adhesive is bonded to a surface of the first substrate.
