Abstract: Pressure-sensitive adhesive compositions and articles that include a layer of the pressure-sensitive adhesive compositions are provided. The pressure-sensitive adhesive compositions are particularly well suited for use with substrates that have been considered to have difficult to bond to surfaces such as those routinely encountered in the automotive industry. For example, the pressure-sensitive adhesive can be adhered to clear coat compositions, painted surfaces, and various polymeric materials having low energy surfaces (e.g., surfaces having a surface energy no greater than 35 dynes per centimeter).

Abstract: An article includes a substrate having a circuit forming surface and a non-circuit forming surface opposite the circuit forming surface. The article further includes a protective tape borne on the circuit forming surface. The protective tape includes a support layer and a curable adhesive layer borne on a major surface of the support layer. The curable adhesive layer includes a rubber elastomer and a thermal curing agent.
