Heat-resistant, paintable two-sided acrylic-based adhesive tape

A heat-resistant, paintable two-sided acrylic-based adhesive tape and method for adhering the tape to two substrates is provided. The tape is comprised of a solid acrylic-based carrier including an acrylic-based adhesive on both sides of the carrier. The carrier preferably includes polymeric microspheres to impart compressibility to the tape. The tape includes a conformable, heat resistant polyolefin-based release liner. In use, the tape is adhered on one side to a first substrate, the liner is removed, and the tape is adhered on the other side to a second substrate. The two substrates with the tape are then exposed to elevated temperatures such as those encountered in an automotive, appliance, or other commercial paint bake process. The tape can withstand temperatures up to 300° F. and can be painted without degradation of the adhesive and without a reduction of the adhesive properties of the tape.
