Description

[0001] Cross references to related patent applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 478969, filed April 26, 2011, and U.S. Provisional Patent Application No. 61 / 500415, filed June 23, 2011, the disclosures of which are incorporated by reference in their entirety. into this article. Background technique [0003] Pressure sensitive tape is virtually ubiquitous in homes and workplaces. In one of its simplest modes, a pressure sensitive tape includes an adhesive and a backing, and the overall construction is tacky at use temperatures and adheres to a variety of substrates using only moderate pressure to form a bond. In this way, the pressure-sensitive adhesive tape constitutes a complete self-sustaining adhesive system. [0004] According to the Pressure Sensitive Tape Association, pressure sensitive adhesives (PSAs) are known to have properties that include: (1) strong and long-lasting adhesion; (2) adhesion with no...
