Abstract:
Provided are adhesive articles and related methods that use a foam layer including an acrylic polymer or silicone polymer and having a pair of opposing major surfaces. An adhesive surface is disposed on each of the opposing major surfaces and a plurality of channels extend across at least one adhesive surface. The adhesive surface defining the channels contains a pressure-sensitive adhesive having a rheology enabling the plurality of channels to essentially disappear over time when the adhesive article is compressed. Advantageously, the provided articles and methods enable high immediate bond and handling strength, a high degree of wet out, weatherability, and superior aesthetics when used with transparent or translucent substrates.
