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 |
20080286536 | Flat Structure That is at Least Partially Provided With a Self-Adhesive Substance - The invention relates to a flat structure that is at least partially provided with a self-adhesive substance, the latter being present on a first surface layer of the flat structure in the form of a plurality of geometric bodies. According to the invention, the surface of at least some of the geometric bodies is at least partially treated in such a way that the treated part of the surface has a lower degree of adhesion than the non-treated self-adhesive substance. | 11-20-2008 |
20090221744 | PROCESS FOR PREPARING A HIGH-COHESION PSA - A process is presented for the preparation of a high-cohesion non-thermoplastic pressure-sensitive adhesive (PSA) on the basis of elastomers, in which neither a solvent nor thermoplastic additives are used and yet thermal breakdown during compounding is kept low. This is achieved through the addition of a vaporizable process agent which is introduced into the adhesive after the constituents have been premixed and which undergoes flash vaporization therein, thereby quenching the adhesive. Furthermore, the use of water to cool the adhesive is proposed, and the high-cohesion PSA thus produced, and also a pressure-sensitive adhesive tape with an adhesive of this kind, are presented. | 09-03-2009 |
20090289381 | METHOD OF ENCAPSULATING OPTOELECTRONIC COMPONENTS - Method of encapsulating optoelectronic components, by embedding the components to be encapsulated between a first transparent polymer layer and a second polymer layer, which is filled with unactivated foaming agent, and then activating the foaming agent, so that the two polymer layers join to one another, in particular weld to one another, and the components are enclosed between the two polymer layers. | 11-26-2009 |
20100014162 | Single or Dual-Sided Adhesive Tape for Protecting Electrochrome Layer Systems on Mirrors - An adhesive tape for protecting electrochromic layer systems on mirrors, having a multilayer carrier consisting of at least one top and one bottom film part, each formed by at least one polymeric film, and also at least one metallic part, which is located between the top and bottom film parts and is formed from a metallic layer of, in particular, aluminum, the exposed side of the bottom film part carrying an adhesive. | 01-21-2010 |
20100147443 | ADHESIVE TAPE, PARTICULARLY FOR BONDING PHOTOVOLTAIC MODULES - The present invention relates to the use of an adhesive tape for adhesively bonding photovoltaic modules, more particularly for adhesively bonding a PV laminate in the frame of a PV module, where the adhesive tape has at least one adhesive layer and where there is at least one polymer layer comprising a foaming agent. | 06-17-2010 |
20100151238 | ADHESIVE TAPE, PARTICULARLY FOR BONDING OPTOELECTRONIC COMPONENTS - An adhesive tape for bonding optoelectronic components comprises a foam layer and two adhesive layers on the outside.

20100178431 | METHOD AND DEVICE FOR THE SOLVENT-FREE PRODUCTION OF ACRYLATE ADHESIVE MASSES - Method for the solvent-free production of acrylate adhesive masses, which comprises (a) continuously coating a mixture, containing one or more photoinitiators and a monomer mixture comprising (i) 70 to 100% by weight compounds selected from the group consisting of (meth)acrylic acid and the derivatives thereof in accordance with the formula | 07-15-2010 |
20110120615 | RADIATION-CROSSLINKABLE FOAMED SELF-ADHESIVE BASED ON VINYLAROMATIC BLOCK COPOLYMERS - Self-adhesive consisting of a mixture having at least one tackifier resin, expanded polymeric microbeads and a polymer blend made up of thermoplastic and/or non-thermoplastic elastomers with at least one vinylaromatic block copolymer containing a fraction of more than 30% by weight of 1,2-linked diene in the elastomer block. | 05-26-2011 |
20110256395 | Pressure-sensitive adhesives based on natural rubber and polyacrylates - A pressure-sensitive adhesive consisting of a homogeneous mixture of at least one natural rubber component and at least one polyacrylate component displays significantly improved properties in cohesion and aging and weathering resistance compared to the individual components. Particularly good properties are achieved when the adhesive contains x% by weight of at least one natural rubber component, y% by weight of at least one polyacrylate component, v% by weight of at least one adhesive resin component and w% by weight of additives, where 10≦×x≦80, 10≦y<95, 0≦v≦50, 0≦w≦10 and x+y+v+w=100. A single- or double-sided adhesive tape consisting of at least one support and at least one layer of such a pressure-sensitive adhesive therefore likewise has good cohesion and aging resistance properties. | 10-20-2011 |
