Abstract: 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. Thus, a stretch releasable adhesive articles of the present disclosure can move freely against the desired mounting surface, develop additional tack and holding power after sufficient pressure is applied.

Abstract: The present disclosure relates to adhesive article that include a first, stretch releasable adhesive and patterned adhesive elements on, within, or partially embedded in a surface of the adhesive. The adhesive elements can act as spacers between the adhesive surface and the mounting surface to prevent full contact and wet out of the first adhesive, whereby the article can be removed from the wall and placed at a new location without damage to the wall surface or the article. Once the final location is selected, the separation created by the engineered elements can be overcome by applying sufficient pressure; the first adhesive can contact and adhere more permanently to the wall. Thus, a stretch releasable adhesive articles of the present disclosure can move freely relative to the desired mounting surface, while developing additional tack and holding power after sufficient pressure is applied.

Abstract: The present disclosure generally relates to adhesive compositions, adhesive articles including the adhesive compositions, methods of making the adhesive compositions and articles, and methods of using the adhesive compositions and articles. The adhesive compositions of the present disclosure include a thermoplastic phenolic resin made from the reaction of (1) alkyl phenol (e.g., butyl- or octyl- or -nonyl) and formaldehyde; or (2) alkyl phenol (e.g., butyl- or octyl-) and acetaldehyde; or (3) alkyl phenol (e.g., butyl- or octyl-) and acetylene. The present disclosure also generally relates to adhesive articles including these adhesive compositions. The inventors of the present disclosure found that such adhesive articles exhibit excellent adhesion to architectural coatings with including low or no VOCs, deep base formulations, and/or formulations including primer in various conditions, including, for example, high humidity.
