Abstract:
Dual-sided adhesive articles include a first crosslinked pressure sensitive adhesive layer with a first major surface and a second major surface, a second siloxane-based pressure sensitive adhesive layer with a first major surface and a second major surface, such that the first major surface of the second siloxane-based pressure sensitive adhesive layer is in contact with the second major surface of the first crosslinked pressure sensitive adhesive layer. The articles also include a release liner having a microstructured surface with an array of microstructures, where the microstructured surface is in contact with the second major surface of the second siloxane-based pressure sensitive adhesive layer. The microstructures of the microstructured surface of the second siloxane-based pressure sensitive adhesive layer are unstable when not in contact with the microstructured release liner, and disappear over time when in contact with a substrate.
