Abstract
Novel one part, heat cured pressure-sensitive adhesives capable of bonding metallic and non-metallic materials at ambient temperatures and curing at elevated temperatures to form a bond with very high adhesive bond strengths at temperatures up to at least 160° C. The invention is particularly well suited for use with insulated copper coils in electrical generators and includes both the adhesive compositions per se and adhesive transfer tapes capable of bonding to the copper coils at ambient temperatures upon contact due to the pressure sensitive tack of the adhesive. The transfer tapes can subsequently be cured to a hard, thermoset adhesive with high adhesive bond strength. In applications on insulated copper coils, exemplary one part, heat cured pressure-sensitive adhesives can be used either alone or in combination with a substrate to form single or double-sided adhesive tape capable of securing the generator rotor turn insulation. The pressure sensitive materials can also be applied to a mat carrier, such as aramid paper, polyester glass, or glass cloth based epoxy sheets.
