Patent number: 11203704Abstract: Hot melt processable adhesive compositions to mask electronic components include at least one block copolymer, at least one tackifying resin, at least one semi-crystalline polyolefin polymer, at least one plasticizer, and at least one anti-oxidant. The adhesive composition is a hot melt processable pressure sensitive adhesive composition that is thermally stable, such that the composition when disposed on a surface withstands heating to 260° C. without degradation or flowing, remains optically transparent, and after heating to 260° C. remains cleanly removable.Type: GrantFiled: March 20, 2019Date of Patent: December 21, 2021Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Richard Yufeng Liu, Yi Lin Sim, Chin Teong Ong, Roger A.

Patent number: 10362717Abstract: Flexible films including an electrically conductive layer being sandwiched by two electrically insulating layers in a layered structure are provided. The layered structure extends continuously from at least one first zone to at least one second zone along a lateral direction of the flexible film, and the at least one first zone is positioned around a periphery of the respective at least one second zone. In the at least one first zone the three layers are at least partially intermixed with each other to provide an electrically conductive surface in the at least one first zone on the side of the first major surface of the layered structure, and in the at least one second zone the first major surface remains electrically non-conductive.Type: GrantFiled: August 17, 2016Date of Patent: July 23, 2019Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Jeanne M. Bruss, Jeffrey W. McCutcheon, Roger A. Grisle

Patent number: 10017670Abstract: Adhesive tape for bonding that can be detached without leaving residue and without damaging the surface of a substrate when stretched in a direction of a bond plane. An adhesive tape includes an elastomeric backing having opposing first and second surfaces an acrylate pressure sensitive adhesive disposed on at least one of the first and second surfaces of the backing. The backing includes a copolymer selected from the group consisting of polyether-polyester, polyether-polyamide, and a combination thereof and from about 20 to 60 wt % of a tackifier, based on the total weight of the backing. The backing has an elongation at break greater than 500%.Type: GrantFiled: February 25, 2013Date of Patent: July 10, 2018Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Roger A.
