In a preferred embodiment, the polymer system is comprised of a hydroxyl functional telechelic diol or polyol polymer and the heterotelechelic polymer is a monohydroxylated polydiene polymer which also has epoxidized olefin functionality. The dual curing system preferably is comprised of an isocyanate curing agent to cure through the hydroxyl groups at ambient temperatures to form a pressure sensitive adhesive or sealant and an amino resin to cure through the epoxy functionality upon baking to form a structural adhesive or sealant.

    Abstract: An electrically conductive adhesive layer includes an adhesive material; a plurality of electrically conductive first particles dispersed in the adhesive material and having a first shape; and a plurality of electrically conductive second particles dispersed in the adhesive material and having a second shape different from the first shape. A ratio of a total weight of the first particles to a total weight of the second particles is in a range from about 2 to about 10. The adhesive layer has an average thickness in a range from about 5 micrometers to about 35 micrometers. An electrical conductance of the adhesive layer in a thickness, but not in an in-plane, direction is at least 5% greater than a comparative adhesive layer having the same construction except that it does not include the second particles.
