20110274843 | Thermally Crosslinking Polyacrylates And Process For Their Preparation - Crosslinker-accelerator system for the thermal crosslinking of polyacrylates with functional groups suitable for entering into linking reactions with cyclic ethers, more particularly epoxide groups or oxetane groups, comprising at least one substance containing epoxide or oxetane grouops (crosslinker) and at least one substance with an accelerating action for the linking reaction at a temperature below the melting temperature of the polyacrylate (accelerator). | 11-10-2011 |
20110100550 | Double-Sided Adhesive Tape for Affixing Protective Sheetlike Structures - Double-sided adhesive tape for affixing large sheetlike structures for the purposes of transit protection and/or assembly protection to substrates such as an automotive finish, consisting of a first adhesive side A comprising an adhesive A with a coatweight of greater than 10 g/m | 05-05-2011 |
20090095428 | HAND-HELD DEVICE FOR UNWINDING AN ADHESIVE TAPE HAVING A DOUBLE-SIDEDLY ADHESIVELY FURNISHED CARRIER, AT LEAST ONE OF THE TWO ADHESIVE SIDES OF THE CARRIER BEING LINED WITH A RELEASE MATERIAL - The invention relates to a hand-held device | 04-16-2009 |
20090081452 | TRANSPARENT ADHESIVE TAPE - A unilaterally bondable, transparent, substantially two-dimensional element (2D element) is presented which has a support and an adhesive, and which is used as a shatterproofing device for brittle 2D bodies. The surface of the support is protected from damage by means of a temporary covering means. The temporary covering means is designed such that it is residue-lessly detachably joined to the support and hence ensures optimal transparency of the 2D element following detachment of the temporary covering means. | 03-26-2009 |
20090081430 | Transparent Adhesive Tape - A construction is presented for a unilaterally bondable, high-transparency, substantially two-dimensional element (2D element) having a support and an adhesive, which is used as a shatterproofing device for brittle 2D bodies. | 03-26-2009 |
20090075011 | Double-Sided Adhesive Tape For Affixing Protective Sheetlike Structures - Double-sided adhesive tape for affixing large sheetlike structures for the purposes of transit protection and/or assembly protection to substrates such as an automotive finish, consisting of a first adhesive side A comprising an adhesive A with a coatweight of greater than 10 g/m | 03-19-2009 |
20090061222 | Multi-layer adhesive closure - The present invention relates to a multi-layer adhesive closure having a backing and an adhesive layer disposed over the full area beneath the backing, at least the following layers being disposed between backing and adhesive layer: a) a first layer applied not over the full area—marking layer; b) a second layer applied over the full area—contrast layer. It is proposed that an individual identifier be included for verification. | 03-05-2009 |
20090047459 | RELEASE AGENT BASED ON ETHYLENE MULTI-BLOCK COPOLYMER - Release agent more particularly for an adhesive with an ethylene multi-block copolymer, the ethylene multi-block copolymer being composed of hard segment blocks, comprising at least 95% (w/w) ethylene and a comonomer, and of soft segment blocks, comprising ethylene and a comonomer, the fraction of comonomer in the soft segment blocks being between 10 and 20 mol %, and the fraction of the hard segment blocks in the ethylene multi-block copolymer being not more than 45% (w/w). | 02-19-2009 |

20080199663 | PROCESS FOR PRODUCING NANOSTRUCTURED AND/OR MICROSTRUCTURED SURFACES IN AN ADHESIVE LAYER, MORE PARTICULARLY IN A SELF-ADHESIVE LAYER - The invention relates to a process for producing nanostructured and/or microstructured surfaces in an adhesive layer, more particularly in a self-adhesive layer, in which an adhesive polymer mixture, more particularly a self-adhesive polymer mixture, is guided into a nip formed by a relief roll, whose surface has been provided with a relief which represents the negative of the surface structure to be produced on the adhesive layer, and by a nip roll, and where the relief roll and the nip roll rotate in opposite directions, wrapped partly around the relief roll is a web-form carrier material which is guided through the nip and whose speed corresponds more particularly to the peripheral speed of the relief roll, the adhesive polymer mixture, more particularly the self-adhesive polymer mixture, is pressed through the nip, so that the near-roll surface of the polymer mixture is shaped in accordance with the relief, lies in layer form on the carrier material after passage through the nip, and is guided away with the carrier material. | 08-21-2008 |
