Publication number: 20210071043Abstract: The present disclosure relates to adhesive article that include a stretch releasable adhesive and topographical, engineered elements on, within, or partially embedded in a surface of the adhesive. The engineered elements can act as spacers between the adhesive surface and the mounting surface to prevent full contact and wet out of the adhesive, whereby the article can be initially positioned or rotated by sliding the surface of the projections across the wall surface. Under certain conditions, the article may even be removed from the wall and placed at a new location without damage to the wall surface or the article. Once the location is selected, the separation created by the engineered elements can be overcome by applying sufficient pressure; the adhesive can contact and adhere more permanently to the wall.Type: ApplicationFiled: May 8, 2019Publication date: March 11, 2021Inventors: Payam Khodaparast, Nishant C. Kumar, Joseph A. Hoffman, Margaret M. Sheridan, Guy M. Kallman, Sara Hemmer Frisco, Nicholas A. Lee, Ann M. Gilman, Matthew R. D. Smith
