Abstract: A UV light curable adhesive is disclosed, comprising, at least one bi-active monomer, at least one polymerizable oligomer, a primary photoinitiator, and a monomer scavenger, wherein photopolymerization of the at least one bi-active monomer by the primary photoinitiator activates the monomer scavenger, reducing residual monomer content in a cured adhesive formed by the photopolymerization of the bi-active monomer in comparison to an otherwise identical comparative UV adhesive lacking the monomer scavenger. A method for curing the UV light curable adhesive is disclosed, including applying the UV light curable adhesive to a surface and exposing the UV light curable adhesive to UV light, free from heating the UV light curable adhesive other than any autogenous increases in temperature from exothermic polymerization reactions. A device with the UV light cured adhesive is disclosed, including the UV light cured adhesive joining a first surface to a second surface.

Abstract: A dissolvable film for delivering a pharmaceutical agent comprises a first water soluble polymer in an amount of from 2 to 35 weight percent and having a molecular weight from about 5,000 daltons to about 49,000 daltons; a second water soluble polymer in an amount of from 2 to 35 weight percent and having a molecular weight greater than 60,000 daltons; and a pharmaceutically active ingredient. The film has a thickness of about 20 microns to about 1200 microns and is configured to disintegrate after contact with a mucous membrane and thereby release the active ingredient.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention provides disintegratable adhesive 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 polysaccharide component, a filler, a plasticizer and/or humectant. The films are preferably in the form of an adhesive layer having a thickness sufficient to disintegrate, when exposed to a moist environment and/or a trigger compound, and release the active ingredient. The films can be cut to any desired size or shape to provide conveniently useable unit dosage forms for administration to wet or moist body surfaces for human, pharmaceutical, cosmetic, or veterinary applications. The invention further provides various end uses and methods of administering the film compositions.

Abstract: A charge collection tape includes a foil substrate and an adhesive layer laminated on the foil substrate. The foil substrate is constructed of an aluminum base foil having a conductive metal coating overlying and in direct contact with a non-oxidized surface of the aluminum base foil.

Abstract: A tape is disclosed. The tape includes a metallic foil, an adhesive layer laminated on one surface of the metallic foil and a protective polymeric coating laminated on an opposing second surface of the metallic foil. The protective coating comprises an anti-corrosion agent. The protective coating shields the metallic foil from corrosion and other drawbacks that can occur by environmental exposure. The tape readily can be employed as a busbar tape in photovoltaic cells to provide a cost-effective substitute for the tin-coated copper currently used there.

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.
