Abstract
The present invention concerns a novel water-insoluble, hydrophilic, pressure-sensitive adhesive that has a number of unique characteristics including being elastomeric and ultraconformable. This adhesive includes an irradiation cross-linked synthetic organic polymer having a three-dimensional matrix, and an adhesive plasticizer. The plasticizer includes a substantially non-volatile elasticizer. The adhesive is useful either as a coating on a supporting web-like substrate or as a self-supporting layer. Also provided are various articles made using the adhesive such as a bandage or ostomy device, a method of making the adhesive, and methods of using the adhesive. In one embodiment, the adhesive is electroconductive, and is useful for attaching an electrically conductive member of an electrode to a selected surface such as mammalian tissue. Also provided is an electrode having a layer of this adhesive, and a method of adhering this electrode to mammalian tissue.
