Abstract
The teachings herein are directed at solid polymeric adhesive compositions for adhering metal components, methods for compounding the polymeric adhesive compositions, articles including a component having the polymeric adhesive composition, methods for producing articles including curing a solid adhesive, and articles including the cured adhesive. Preferred solid polymeric adhesive compositions include a plurality of one or more epoxy resins and one or more polysulfones. In one preferred aspect, the teachings are directed at a stator ring (e.g., for a hybrid motor) including the polymeric adhesive composition for adhering components to a ring.
