Publication number: 20240084125Abstract: A curable composition comprising 20 wt. % to 60 wt. %, optionally 30 wt. % to 58 wt. %, or optionally 40 wt. % to 55 wt. % of an acrylic block copolymer, 5 wt. % to 60 wt. %, optionally 20 wt. % to 50 wt. %, or optionally 15 wt. % to 45 wt. %, of an epoxy resin; 1 wt. % to 60 wt. %, optionally 5 wt. % to 50 wt. %, or optionally 15 wt. % to 45 wt. %, of a polyol; and 0.5 wt. % to 10 wt. %, optionally 0.75 wt. % to 8 wt. %, or optionally 1 wt. % to 5 wt. %, of a curing agent. The curable composition may be used to prepare a tape that is initially soft (i.e., low-modulus), which enables a water-tight seal during an electronics assembly process at ambient temperatures, and then cures after UV-activation into a more rigid (i.e., higher modulus) tape that has a desirable balance of impact resistance (both tensile and shear impact), dynamic shear resistance, and pushout resistance.Type: ApplicationFiled: December 23, 2021Publication date: March 14, 2024Inventors: Jonathan E. Janoski, Andrew Satrijo, Kathleen S. Schafer, Adam O. Moughton

Patent number: 11059999Abstract: The present invention relates to a double-sided adhesive tape used for applications including the attachment of front glass for mobile devices. A core layer of the double-sided adhesive tape is prepared by adding an acrylic elastomer free of carbon-carbon double bonds while being highly miscible with an acrylic resin to an acrylic monomer(s) and performing curing, and thus can improve the impact resistance of the final double-sided adhesive tape. Also, the core layer may take a form of foam due to the introduced filler such as glass bubbles or organic microspheres, and thus can further contribute to improving the impact resistance of the final double-sided adhesive tape.Type: GrantFiled: May 24, 2017Date of Patent: July 13, 2021Assignee: 3M Innovative Properties CompanyInventors: Seongwoo Kim, Yong Seok Seo, Do-Kwang Cho, You Hoon Kim, Andrew Satrijo, Ross J. DeVolder

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.
