Publication number: 20060246282Abstract: The invention relates to a two-side self-adhesive tape whose sides have different adhesive forces and are provided with at least one adhesive layer. Said invention is characterised in that the glue of the less adhesive layer is based on ethylene vinyl acetate copolymer whose vinyl acetate part in the copolymer ranges from 25 to 92 mass %. in a preferred embodiment from 40 to 70 mass %, the adhesive substance can be possibly mixed to additives such as adhesive resins, softeners, antioxidants and fillers.Type: ApplicationFiled: August 12, 2004Publication date: November 2, 2006Inventors: Nicolai Bohm, Carsten Bohmer, Philippe Hesse, Nataly Hoppe, Uwe Schumann, Sianty Sunarto

Patent number: 7091300Abstract: Polyurethane-based pressure-sensitive adhesive which attaches strongly to polar plastic surfaces, smooth metal surfaces and glass, but which has weak, if any, adhesion to paper, paperboard or skin and is easily detachable without damaging surfaces during its removal, and is reusable. The adhesive comprises a polyurethane formed by reacting an aliphatic or alicyclic polyisocyanate having a functionality of equal to or less than three with a combination of diol and triol.Type: GrantFiled: April 1, 2004Date of Patent: August 15, 2006Assignee: tesa AktiengesellschaftInventors: Bernd Lühmann, Philippe Hesse, Sianty Sunarto, Uwe Schümann, Kirstin Weiland, Carsten Böhmer

Publication number: 20050019560Abstract: Disclosed is a double-sided pressure-sensitive adhesive tape having sides which differ in adhesive strength, and a method for its preparation. The double-sided pressure-sensitive adhesive tape comprises at least one adhesive layer comprising a pressure-sensitive adhesive based on a chemically crosslinked polyurethane. The double-sided pressure-sensitive adhesive tape is especially well-suited to adhere flexible storage media, such as CDs, CD-ROMs and DVDs, to curved, bent or creased surfaces. The double-sided pressure-sensitive is also especially well-suited for adhering customer cards and credit cards to paper.Type: ApplicationFiled: April 16, 2004Publication date: January 27, 2005Applicant: Tesa AktiengesellschaftInventors: Philippe Hesse, Carsten Bohmer, Sianty Sunarto, Uwe Schumann, Nataly Hoppe
