Patent number: 11472156Abstract: The present disclosure generally relates to conformable adhesive articles that are capable of attaching or adhering to a substrate and that can be removed from the substrate without causing damage to the substrate. The present disclosure also generally relates to methods of making and using such adhesive articles. In some embodiments, the adhesive article includes (1) a releasable layer having a first major surface and a second major surface; the second major surfaces including a pressure sensitive adhesive capable of adhering the adhesive article to a surface; and (2) a compliant layer having a first major surface and a second major surface; the second major surface of the compliant layer adjacent to the first major surface of the releasable layer. In some embodiments, the releasable layer debonds from both the surface and the compliant layer when the adhesive article is stretch released at an angle of less than 35 degrees.Type: GrantFiled: March 26, 2018Date of Patent: October 18, 2022Assignee: 3M Innovative Properties CompanyInventors: Megan P. Lehmann, David J. Yarusso, Christina D. Cowman-Eggert, Barbara K. Schmotter, Corinne E. Lipscomb

Patent number: 9828532Abstract: Crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions, which include two (meth)acrylate copolymers plus a tackifier, are used to form the crosslinked compositions upon exposure to ultraviolet radiation. The crosslinked compositions can function as pressure-sensitive adhesives. The crosslinkable compositions are well suited for use with hot melt processing methods.Type: GrantFiled: November 5, 2013Date of Patent: November 28, 2017Assignee: 3M INNOVATION PROPERTIES COMPANYInventors: Anish Kurian, Jason D. Clapper, Ross E. Behling, Megan P. Lehmann, David J. Yarusso, Babu N. Gaddam, Mark F. Ellis

Patent number: 9695343Abstract: The methods of preparing hot melt processable pressure sensitive adhesives include combining an elastomeric (meth)acrylate random copolymer and a discontinuous fibrous material in a hot melt mixing apparatus, and mixing to form a hot melt processable pressure sensitive adhesive. The elastomeric (meth)acrylate random copolymer may be contained within a thermoplastic pouch, and the hot melt mixture may include a relatively high level of tackifying resin. The elastomeric (meth)acrylate random copolymer may contain branching agents and photosensitive crosslinking agents. The hot melt processable pressure sensitive adhesives can be used to prepare transfer tapes.Type: GrantFiled: September 23, 2011Date of Patent: July 4, 2017Assignee: 3M Innovative Properties CompanyInventors: Andrew Satrijo, Megan P. Lehmann, Nathan B. Fong, Craig E. Hamer, John R. Jacobsen, Mark F. Ellis

Patent number: 9574117Abstract: Adhesives suitable for use with low surface energy materials are described. The adhesive contain an acrylic copolymer, a high glass transition temperature tackifier and a low glass transition temperature tackifier. The acrylic copolymer is the reaction product of a first alkyl(meth)acrylate having at least 5 carbon atoms in the alkyl group, a second alkyl(meth)acrylate having 1 to 4 carbon atoms in the alkyl group, and a vinyl carboxylic acid. Both tackifiers have a Tg greater than the Tg of the acrylic copolymer. The high glass transition temperature tackifier has a Tg of at least 20° C. and the low glass transition temperature tackifier has a Tg of less than 0° C.Type: GrantFiled: December 28, 2015Date of Patent: February 21, 2017Assignee: 3M Innovative Properties CompanyInventors: Jingjing Ma, Zhong Chen, Megan P. Lehmann, Michael L. Tumey, Dong-Wei Zhu
