Described are adhesive compositions containing a mixture of a pressure sensitive adhesive, a high Tg polymer, and a crosslinker to form a compatibilized blend that is optically clear. Methods of using the adhesive compositions, and multilayer assemblies such as optical elements prepared using the adhesives, are also provided.

Adhesive blends, articles, and methods

Pressure sensitive adhesive compositions comprising an unreactive mixture of polydiorganosiloxane polyurea copolymer, diluent, and silicate tackifying resin. The compositions are useful for articles such as medical devices.

Silicone pressure sensitive adhesive and articles

An iodine/iodide-containing hot melt coatable adhesive is provided. This adhesive is prepared by mixing iodine and an iodide salt, individually or in combination, with solubilizing liquids. The iodine and iodide salt are combined with a pre-adhesive composition in a hot melt mixer, with an iodine/iodide complexing agent being present in the mixture. The mixture is mixed at a temperature from about 130&#xb0; C. to about 200&#xb0; C. and sufficiently to form an iodine/iodide-containing hot melt coatable adhesive. Alternatively, the iodide may be generated in situ. The adhesive so prepared may be packaged for coating on a substrate at a later time, or may be immediately coated to form an adhesive composite. Adhesive composites, particularly surgical incise drapes, are provided incorporating this hot melt coatable adhesive.

Iodine/iodide-containing hot melt coatable adhesive, methods and uses therefor

A light managing screen may provide a rear projection screen, front projection screen or component thereof. The screen may comprise a polymeric composition including a first polymeric material, and a second polymeric material disposed as a plurality of elongated structures within the first polymeric material. Each elongated structure has a major axis and the major axes are substantially aligned. The first polymeric material has an index of refraction that differs by at least 0.01 from an index of refraction of the second polymeric material. In some instances, a pressure sensitive adhesive material is selected as the first polymeric material. The orientation of the elongated structures and the difference in indices of refraction results in the polymeric composition scattering light asymmetrically.

Light emitting diode (LED) device and method of making same

A shock indicator is described comprising (A) a base having a first side and a second side; (B) an indicator associated with the first side of the base, the indicator comprising a plurality of indicator subparts, the subparts comprising solid material arranged (i) in a first configuration when the shock indicator is in a first state prior to a shock event, and (ii) in a second configuration when the shock indicator is in a second state following a shock event; and (C) means associated with the second side of the base for attachment of the shock indicator to a surface. A method of manufacture is also provided.

Priming compositions and methods, wherein the compositions include a polydiorganosiloxane polyurea copolymer comprising electron rich groups.

Silicone priming compositions, articles, and methods

Pressure sensitive adhesive articles and methods, particularly stretch removable adhesive articles that are preferably for use in adhering to skin or like delicate surfaces. Preferably, stretch removability of the article occurs as a result of the selection of a stretch removable pressure sensitive adhesive. In one embodiment of the articles and methods, the adhesive and backing delaminate upon removal. In another embodiment of the articles and methods, the backing includes a predefined tab located in a central location of the backing.

Stretch removable adhesive articles and methods

A foam adhesive article is provided comprising a polymeric foam material having an outer surface, the outer surface of the polymeric foam material having adhesive properties; and fibrous reinforcing material, the fibrous reinforcing material dispersed within the polymeric foam material and imparting stretch release properties to the article. A method for preparing the foam adhesive article is also described comprising (a) melt mixing a foamable polymer composition, and a fiber forming resin to form an expandable extrudable composition; and (b) extruding the expandable extrudable composition through a die to provide the foam adhesive article.

Stretch releasable foams, articles including same and methods for the manufacture thereof

This invention is directed to a reinforced adhesive fiber that includes a pressure sensitive adhesive component and a reinforcing material within the pressure sensitive adhesive component.

Pressure sensitive adhesive fibers with a reinforcing material

Projection screen having elongated structures

The present invention provides a multi-layer tape, comprising: a first adhesive layer comprising a pressure sensitive adhesive; a core layer having an outer surface, the first adhesive layer adhered to at least a portion of the outer surface; and fibrous reinforcing material dispersed within the core layer, the fibrous reinforcing material imparting stretch release properties to the tape. The tape may comprise a second adhesive layer wherein the outer surface comprises a first major surface and a second major surface, the first adhesive layer being adhered to the first major surface, and the second adhesive layer being adhered to the second major surface. A fire retardant may be disposed in any of the first adhesive layer, the second adhesive layer, and the core layer. The tape may be cleanly removable. The fibrous reinforcing material typically comprises substantially continuous viscoelastic microfibers having a yield strength and a tensile break strength, and the tensile break strength is at least about 150% of the yield strength. In another aspect, the tapes of the invention may be formulated to be cleanly removable without including fibrous reinforcing material therein. The invention also provides a method for the manufacture of the foregoing tape as well as an assembly comprising: a substrate; a carpet overlying the substrate; and a tape according to the invention disposed between the carpet and the substrate and adhering the carpet to the substrate.

Cleanly removable tapes and methods for the manufacture thereof

The invention provides an assembly for the control and removal of fluids, the assembly comprising: A fluid control layer having a top side and a bottom side, the top side constructed to facilitate the evaporation or the flow of a fluid disposed thereon; a fire retardant material having a first major surface and a second major surface, the first major surface associated with the bottom side of the fluid control layer, the fire retardant material comprising a polymer; and an adhesive layer associated with the second major surface of the fire retardant material. A fluid management system for aircraft and a method for the use of the system in aircraft are also described.
