Publication number: 20210230456Abstract: An adhesive tape for bonding low-energy surfaces, comprising a UV cross-linked pressure-sensitive adhesive compound which comprises poly-acrylate, a linear or branched vinyl aromatic block co-polymer and at least one adhesive resin. The UV cross-linking of the pressure-sensitive adhesive compound is the result of irradiation with UV-A-containing light.Type: ApplicationFiled: August 2, 2019Publication date: July 29, 2021Applicant: LOHMANN GMBH & CO.

Patent number: 10717905Abstract: The invention relates to an adhesive compound containing a multi-armed vinyl aromatic block copolymer, one or more adhesive resins, and one or more auxiliary crosslinking agents. The invention also relates to an adhesive means comprising said adhesive compound and a carrier material and/or a cover. The invention also relates to a method for producing such an adhesive means. Compared to adhesive systems known up until now, such an adhesive means demonstrates clearly improved adhesion to hard, non-polar surfaces such as, for example, novel coated surfaces in the automotive industry.Type: GrantFiled: June 17, 2016Date of Patent: July 21, 2020Assignee: LOHMANN GMBH & CO.
