20140287181 | HYDROPHILIC ADHESIVES AND TAPES AND DEVICES CONTAINING THE SAME - Hydrophilic adhesive compositions are disclosed that contain a surfactant that is miscible, but not fully soluble in the polymer matrix of the adhesive. This permits the surfactant to continuously replenish at the surface of the adhesive as other surfactant is removed, such as when it is carried away by an aqueous sample flowing over that surface in an in-vitro diagnostic device, resulting in adhesive compositions that are inherently hydrophilic on their surfaces and do not rely on the bloom mechanism of known hydrophilic adhesives. This provides greater design options for in-vitro diagnostic device manufacturers, including the use of hydrophilic adhesive spacers in lieu of or in combination with hydrophilic top covers. | 09-25-2014 |
20140158296 | REACTIVE FILM ADHESIVE - An actinic radiation activated, thermally curable solid film adhesive is disclosed that includes a film forming polymeric binder, a cationically curable resin, and a cationic photoinitiator. The solid film adhesive is capable of being processed at temperatures up to 120° C. prior to exposure to actinic radiation without curing, has a latency period at room temperature following activation of the initiator, and is curable at temperatures above 50° C. following activation of the initiator. | 06-12-2014 |

20130233485 | REACTIVE CONDUCTIVE PRESSURE-SENSITIVE ADHESIVE TAPE - A reactive pressure sensitive adhesive composition is disclosed. A tape formed using the reactive pressure sensitive adhesive is also disclosed. In its cured state, the pressure sensitive adhesive shows superior mechanical and electrical properties compared to conventional, non-curable charge collection tapes. The tape has a cure profile pre-selected to correspond to that of a photovoltaic cell fabrication process, such that curing can take place during cell fabrication and may occur simultaneously with one or more other curing steps employed in cell fabrication. | 09-12-2013 |
20130095156 | RAPIDLY DISINTEGRATING FILMS FOR DELIVERY OF PHARMACEUTICAL OR COSMETIC AGENTS - The invention provides disintegratable films containing a mixture of high molecular weight and low molecular weight water soluble components; and a pharmaceutically or cosmetically active ingredient. Optionally, the films contain a starch component, a glucose component, a filler, a plasticizer and/or humectant. The films are preferably in the form of a mucoadhesive monolayer having a thickness sufficient to rapidly disintegrate in the oral environment and release the active ingredient without undue discomfort to the oral mucosa. The monolayer can be cut to any desired size or shape to provide conveniently useable unit dosage forms for administration to oral or other mucosal surfaces for human pharmaceutical, cosmetic, or veterinary applications. The invention further provides methods of administering the film compositions by placing the composition into, for example, the oral cavity for a sufficient period of time to permit the film to disintegrate and release the active ingredient. | 04-18-2013 |
20120283615 | PRESSURE SENSITIVE ADHESIVE FOR APPLICATION ON SKIN AND PROCESS FOR THE PRODUCTION THEREOF - Pressure sensitive adhesives for use primarily in medical applications are disclosed. The pressure sensitive adhesives are urethane elastomeric adhesives that include a polyurethane polymer and a compatible tackifier and/or compatible plasticizer to achieve an adhesive having a predetermined compliance. The result is a pressure sensitive adhesive for application to skin that can eventually be removed with very little trauma to the skin and with a low pain rating, but which still exhibits very good peel strength when used to construct an article in which the adhesive is adhered to human skin. | 11-08-2012 |

20100068820 | MOLECULARLY IMPRINTED POLYMER AND USE THEREOF IN DIAGNOSTIC DEVICES - An adhesive is provided containing at least one synthetic polymer with receptor sites that enable the selective capture or release of a target molecule. A polymer is synthesized by polymerizing and cross-linking a functional monomer or functional copolymers in the presence of a target or template molecule allowing for reversible interactions between the polymer and the target molecule. The target molecule may be extracted from the polymer creating receptor sites complimentary to the target molecule. Alternatively, the target molecule may remain in the polymer network and be controllably released. The molecularly imprinted polymer is formulated into an adhesive. The adhesive can be used as a component in an in-vitro diagnostic device to release template molecules or to capture target molecules in vacated receptor sites in the synthetic polymer. | 03-18-2010 |

20090029100 | METHOD FOR PRODUCING RIGID LAMINATES FOR OPTICAL APPLICATIONS - A method for fabricating a rigid lamination. The method includes providing a first rigid substrate, disposing an adhesive on a surface of the first rigid substrate and disposing a second rigid substrate on at least a portion of the adhesive. The second rigid substrate has a first end and a second end. The second rigid substrate is heated to a substantially uniform temperature, where the temperature is sufficient to melt the adhesive. A non-uniform pressure is applied to a surface of the second rigid substrate. The non-uniform pressure includes a lesser pressure and a greater pressure, where the greater pressure is applied at the first end of the second rigid substrate and is sufficient to impart adhesive flow in a direction toward the second end. The pressure is controllably increased along at least a portion of the surface between the first end and the second end, where the increase is controlled to drive the adhesive flow in the direction toward the second end until the pressure applied is substantially uniform across the surface and the adhesive between the first rigid substrate and the second rigid substrate is substantially free of entrained gas bubbles. The adhesive is cooled to form a rigid lamination having adhesive substantially free of entrained gas bubbles. | 01-29-2009 |
