Embodiment Construction

[0099] A series of evaluations were performed using the liner and non-adhesive components described herein to assess the repositionability or slip characteristics of the bonded articles. In particular, samples embodying the present subject matter and marked with the "RS" suffix are compared to the corresponding samples. Specifically, the subject "RS" samples were compared to equivalent counterparts having the same bonded component construction and materials as the RS samples. However, as described herein, the RS samples included a liner assembly with a deformable layer and an effective amount of a non-adhesive component disposed along its release face. Comparisons were made by subjecting two sets of samples to one or more of the following tests: (i) 180 degree peel adhesion on stainless steel for different dwell periods, (ii) static shear evaluation, (iii) loop tack, and (iv) Shear Adhesion Failure Test (SAFT).

Abstract

Adhesive articles and release liners are described. The release liners include nonadhesive components such as nonadhesive particulates along their release face. Upon incorporation in an adhesive article and exposure of an adhesive face thereof, at least a portion of the nonadhesive components are carried along the adhesive face. The release liners also include a deformable layer. The inclusion of the deformable layer in the release liner and the inclusion of the nonadhesive components in the adhesive region imparts repositionable or slidability characteristics to the article.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 818,645, filed May 2, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] The subject matter relates to adhesive articles, release liners, and related methods of making and using. The adhesive articles and release liners may find usefulness in a variety of applications including, for example, advertising and promotion, screening and coloring, transportation, traffic and security, signage, and industrial and graphic displays. In particular, the subject matter will find wide application in industrial adhesive tapes. Background technique [0004] Pressure sensitive adhesives are used in a variety of applications including tapes, labels and other bonded articles. Pressure sensitive adhesives have many advantages such as strong cohesion and ease of application. A disadvantage of these products is the stro...
