Publication number: 20210102095Abstract: Curable adhesive free-standing films and adhesive systems comprising such films are provided. In some embodiments, a curable adhesive free-standing film comprises a blend of: a) a first film-forming polymer or oligomer; b) a first species comprising first unsaturated free-radically polymerizable groups, which may be a) or a species other than a); c) a first transition metal cation; d) a reducing agent; and no oxidizing agent. In some embodiments, an adhesive system comprises: I) a first curable adhesive free-standing film as described preceding; and II) a second curable adhesive free-standing film comprising a blend of: e) a second film-forming polymer or oligomer; f) a second species comprising second unsaturated free-radically polymerizable groups, which may be e) or may be a species other than e); and g) an oxidizing agent. In some embodiments, the curable adhesive free-standing films may be pressure sensitive adhesives prior to cure. Methods of use are provided.Type: ApplicationFiled: February 8, 2019Publication date: April 8, 2021Inventors: Shantanu R. Ranade, Alexander J. Kugel, Kai U. Claussen, Rachna Khurana, Dean M. Moren, William H. Sikorski, JR., Erik M. Townsend

Publication number: 20210102097Abstract: Curable adhesive films, primers for adhesion of curable adhesive films, and adhesive systems comprising adhesive films and primers are provided. In some embodiments, an adhesive system comprises: I) a curable adhesive free-standing film comprising a blend of: a) a first film-forming polymer or oligomer; b) a first species comprising first unsaturated free-radically polymerizable groups, which may be a) or a species other than a); and c) a first transition metal cation; and II) a primer for adhesion of a curable adhesive free-standing film to a first substrate comprising an oxidizing agent. In some embodiments, an adhesive system comprises: I) a curable adhesive free-standing film comprising an outer surface bearing embossed air bleed channels capable of aiding in escape of air during application of the outer surface to a primed substrate; and II) a primer comprising components that initiate cure of the curable adhesive free-standing film.Type: ApplicationFiled: February 8, 2019Publication date: April 8, 2021Inventors: Shantanu R. Ranade, Alexander J. Kugel, Kai U. Claussen, Rachna Khurana, Dean M. Moren, William H. Sikorski, Jr., Erik M. Townsend

Patent number: 10272655Abstract: A film comprising stripes alternating with strands is disclosed. In some embodiments, the strands have a core and a sheath. The core is more elastic than both the sheath and the strands. In some embodiments, the film has an elongation of at least 75 percent, the width of the strands is in a range from 100 micrometers to 750 micrometers, and a portion of each strand forms part of at least one major surface of the film. An extrusion die useful for making the film and a method for making the film using the extrusion die are also disclosed.Type: GrantFiled: October 2, 2012Date of Patent: April 30, 2019Assignee: 3M Innovative Properties CompanyInventors: Thomas P. Hanschen, Ronald W. Ausen, Paul S. Wallis, William J. Kopecky, Vathsala Rajagopal, William H. Sikorski, Jr.

Patent number: 9944043Abstract: An incrementally activated laminate that includes an incrementally activated fibrous web and a film having alternating first and second regions and a laminate of the film and an extensible fibrous web. The first region of the film includes a first polymeric composition, and the second regions include an elastic polymeric composition that is more elastic than the first polymeric composition. In the incrementally activated laminate, the distance between midpoints of two first regions separated by one second region is smaller than the activation pitch, and the first regions are not plastically deformed. In the extensible laminate, a tensile elongation at maximum load of the film is up to 250 percent of the tensile elongation at maximum load of the extensible fibrous web. Methods of making the laminates are also described.Type: GrantFiled: October 2, 2012Date of Patent: April 17, 2018Assignee: 3M Innovative Properties CompanyInventors: Thomas P. Hanschen, William H. Sikorski, Jr., Ronald W. Ausen, Paul S. Wallis, Vathsala Rajagopal, William J. Kopecky

Publication number: 20170087029Abstract: A method of making a breathable, elastic film laminate comprising the steps of stretching an elastic film in a first direction, spot welding at least one nonwoven web to the film while it is stretched, and stretching the film laminate in a second direction to create apertures in the film. Articles derived from the method are also described.Type: ApplicationFiled: April 27, 2015Publication date: March 30, 2017Inventors: Todd L. Nelson, Robert E. Andrews, William H. Sikorski, Jr.

Patent number: 9469091Abstract: A method of making extensible web laminates comprising a multilayer film and at least one web layer and the use of such extensible web laminates in personal care articles. The method generally includes activating the multilayer film in a first direction by stretching at least a portion of the multilayer film past the elastic deformation limit of the skin layers and recovering the skin layers with the elastomeric core layer to produce a multilayer film that is elastic in the first direction. The activated multilayer film is subsequently stretched beyond the deformation limit of the skin layers in a second direction substantially perpendicular to the first direction. At least one web layer is applied to the multilayer film while in the stretched state. The multilayer film is then recovered to produce an extensible web laminate.Type: GrantFiled: August 8, 2012Date of Patent: October 18, 2016Assignee: 3M Innovative Properties CompanyInventors: Mary Beth Henke, Rebecca A. Shipman, Gerald S. Deeb, Kent R. Schoenherr, Todd L. Nelson, William H. Sikorski, Jr., Vathsala Rajagopal, Thomas P. Hanschen, Mark A. Peltier
