20110151249 | PRESSURE-SENSITIVE ADHESIVE TAPE AND METHOD OF MANUFACTURING THE PRESSURE-SENSITIVE ADHESIVE TAPE - A pressure-sensitive adhesive tape is provided with a pressure-sensitive adhesive layer and a water-repellent layer formed on the pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer. The water-repellent layer is formed by using a water repellent exhibiting the water repellency in which a contact angle with water is greater than or equal to 140°. The water-repellent layer may have hydrophobic fine particles. The hydrophobic fine particle may contain a hydrophobic fine silica compound. The hydrophobic fine silica compound may be modified with hexamethyldisilazane. | 06-23-2011 |
20110250446 | PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND ACRYLIC PRESSURE-SENSITIVE ADHESIVE TAPE - A pressure-sensitive adhesive composition or an acrylic pressure-sensitive adhesive tape in which peeling-off property or tearing-off property occurring by heating is improved while the high adhesiveness to a metallic material is being maintained, will be provided. The pressure-sensitive adhesive composition contains: an acrylic polymer (A); a (meth)acrylic polymer (B) whose mass average molecular weight (Mw) is such that 1000≦Mw<30000; and a heat-expandable microsphere (C). | 10-13-2011 |
20120034447 | HEAT-EXPANDABLE REMOVABLE ACRYLIC PRESSURE-SENSITIVE ADHESIVE TAPE OR SHEET - Provided is a heat-expandable removable acrylic pressure-sensitive adhesive tape that has high normal-state adhesive power when bonded independently of whether the adherend has or does not have irregular surface and permits easy separation when the bonded region is separated and disassembled by lowering the adhesive power by heating, that permits easily separation-decomposition, even after long-term storage at high temperature. | 02-09-2012 |
20120040177 | HEAT-EXPANDABLE REMOVABLE ACRYLIC PRESSURE-SENSITIVE ADHESIVE TAPE OR SHEET - Provided is a heat-expandable removable acrylic pressure-sensitive adhesive tape that has high normal-state adhesive power when bonded independently of whether the adherend has or does not have irregular surface and permits easy separation when the bonded region is separated and disassembled by lowering the adhesive power by heating, that permits easily separation-decomposition, even after long-term storage at high temperature. | 02-16-2012 |
20120148791 | PRESSURE-SENSITIVE ADHESIVE TAPE OR SHEET - Disclosed is a pressure-sensitive adhesive tape or sheet having an adhesive face which includes two or more different pressure-sensitive adhesives each capable of acting on an adherend and exhibits adhesiveness and debonding capability both at high levels. The pressure-sensitive adhesive tape or sheet has an adhesive face being substantially smooth and including at least on region composed of a first pressure-sensitive adhesive and at least one region composed of a pressure-sensitive adhesive other than the first pressure-sensitive adhesive. In the pressure-sensitive adhesive tape or sheet, the region composed of the first pressure-sensitive adhesive and the region composed of the other pressure-sensitive adhesive than the first pressure-sensitive adhesive preferably are preferably in the form of stripes extending in the longitudinal direction. | 06-14-2012 |
20120276378 | DOUBLE-COATED PRESSURE-SENSITIVE ADHESIVE SHEET FOR OPTICAL USE - An object of the present invention is to provide a double-coated pressure-sensitive adhesive sheet for optical use satisfying both high corrosion resistance and adhesion reliability. The double-coated pressure-sensitive adhesive sheet for optical use according to the present invention has a pressure-sensitive adhesive layer having a resistance ratio determined by a specific corrosion resistance test of from 90 to 120 and an average air bubble diameter of air bubbles determined by a specific bubbling delamination resistance test of 1.0 mm or less. Further, the double-coated pressure-sensitive adhesive sheet for optical use according to the present invention preferably has a total light transmittance of 90% or more and a haze of 1.5% or less. | 11-01-2012 |
20130009105 | CONDUCTIVE PRESSURE-SENSITIVE ADHESIVE TAPE - A conductive pressure-sensitive adhesive tape contains an acrylic pressure-sensitive adhesive, a conductive filler, and a heating foaming agent. An acrylic polymer can be preferably used as the acrylic pressure-sensitive adhesive. With the multiple conductive fillers being electrically connected to each other, conductive paths communicating from one of the major surfaces of the tape to the other major surface thereof are formed before temperature sensing. The heating foaming agent is a heating-type foaming agent that is foamed by being heated. The electrical connection between the conductive fillers, which has been formed before the heating foaming agent is foamed, is disconnected by the foamed heating foaming agent, and the conductive paths communicating from one of the major surfaces of the tape to the other major surface thereof are eliminated. | 01-10-2013 |
20130081764 | HEAT-EXPANDABLE REMOVABLE PRESSURE-SENSITIVE ADHESIVE TAPE OR SHEET, AND METHOD OF REMOVING THE SAME - The heat-expandable removable pressure-sensitive adhesive tape of the present invention includes at least a blowing agent-containing pressure-sensitive adhesive layer A, a microparticle-containing viscoelastic substrate B, a peelable or peel-assisting film layer C, and a pressure-sensitive adhesive layer D. A multilayer structure containing at least the peelable or peel-assisting film layer C and the pressure-sensitive adhesive layer D is arranged on at least one side of the blowing agent-containing pressure-sensitive adhesive layer A where the blowing agent-containing pressure-sensitive adhesive layer A is in direct contact with the peelable or peel-assisting film layer C. The peelable or peel-assisting film layer C can be removed from the blowing agent-containing pressure-sensitive adhesive layer A by heat treatment after storage in an atmosphere of 75° C. for 8 weeks. | 04-04-2013 |
