The disclosed medical dressing has a dressing body and a flap. The dressing body has a first major surface and opposite second major surface containing a skin-contact adhesive. The flap has a fixed end integrally connected to the dressing body and a movable free end. The second major surface of the flap has a securing adhesive for contact with the first major surface of the dressing body.

Medical dressing comprising a flap

Adhesive compositions are provided that contain a crosslink product resulting from exposure of a (meth)acrylic-based composition to electron beam radiation, gamma ray radiation, or both. More particularly, the (meth)acrylic-based composition includes a (meth)acrylic-based diblock copolymer and an optional (meth)acrylic-based triblock copolymer. These adhesive compositions are particularly well suited for application to biological surface such as skin.

Adhesive compositions with (meth)acrylic-based block copolymers

A medical dressing () with a dressing body () and a flap (). The flap can include a fixed end () coupled to the dressing body, and a free end () movable with respect to the dressing body between a first position and a second position in which the free end is positioned in overlapping relationship with the dressing body. A second major surface () of at least the free end of the flap can be configured to be secured to the dressing body, and the flap can be located toward a proximal end of the dressing body, such that a distal portion of the dressing body is free of the flap. The dressing body can be adhered to skin with a skin-contact adhesive (e.g., a silicone adhesive) (), and the flap can be secured to the dressing body with a securing adhesive (e.g. an acrylate adhesive) () that can have a higher adhesion or adhesive strength.

Adhesive articles that include a substrate and a silicone adhesive are disclosed. The articles also include a polymer containing poly(propylene oxide) units and optionally poly(ethylene oxide) units and having a number average molecular weight of at least 1000 grams per mole. The polymer may either be incorporated into the substrate or may be used as a primer on the substrate. If the polymer includes poly(ethylene oxide) units, the copolymer typically has a weight ratio of poly(ethylene oxide) to poly(propylene oxide) of up to 3:1, or if the copolymer has a number average molecular weight of at least 10,000 grams per mole, the weight ratio of poly(ethylene oxide) to poly(propylene oxide) is up to 2:1. Methods of making the adhesive articles are also disclosed.

Adhesive article and method of making the same

Adhesive compositions are provided that include a crosslinked silicone gel, a hydrophilic component dispersed in the silicone gel, and an antimicrobial agent dispersed in the silicone gel. The adhesive composition is readily applied to (and removed from) skin, and has desirable hydrophilic and antimicrobial properties. Advantageously, the hydrophilic component in the crosslinked silicone gel is not readily extractable (e.g., into a pH 7 buffer). Surprisingly, the combination of hydrophilic component with antimicrobial agent in the crosslinked silicone gel can provide a synergistic level of antimicrobial activity.

Silicone gel adhesive with hydrophillic and antimicrobial properties

Curable compositions include at least one polydiorganosiloxane with at least two hydroxysilyl moieties, at least one hydroxyl-functional polyorganosiloxane resin, and at least one photoactivatable composition that, upon exposure to radiation, generates at least one base selected from amidines, guanidines, phosphazenes, proazaphosphatranes. The curable compositions can be coated on substrates and cured to form coatings, including pressure sensitive adhesives.

Curable polysiloxane compositions and pressure sensitive adhesives made therefrom

Blended, release materials containing crosslinked silicones, crosslinked fluorosilicones, and nonfunctional fluorosilicones are described. Articles including release liners and adhesive articles are also described, as are methods of making such blended release materials and articles incorporating them.

Blended release materials

Adhesive articles that include a substrate, a silicone polyoxamide-containing primer layer, and a silicone adhesive are disclosed. Methods of making the adhesive articles and the use of a silicone polyoxamide as a primer for improving adhesion between a substrate and a silicone adhesive are also disclosed.

An adhesive tape that is stretch releasable, articles that contain the adhesive tape, and uses of the adhesive tape are disclosed. The adhesive tapes include a backing layer that is adjacent to at least one pressure-sensitive adhesive layer. The backing layer typically is optically clear and includes a poly(alkylene) copolymer. The pressure-sensitive adhesive layer is a silicone-based adhesive composition. In many embodiments, the adhesive tape is optically clear.

Electron beam and gamma radiation crosslinked, silicone gel adhesives are described. Both nonfunctional and functional poly diorganosiloxanes are used. Methods of forming the adhesives, and medical articles incorporating such adhesives are also described.

Gentle to skin adhesive

Surface-modified zirconia nanoparticles and methods for making and using the same are provided. The surface-modifiers include non-metallic organic derivatives, comprising at least one hydroxamate functionality, wherein at least some of the non-metallic organic derivatives are attached to at least some of the zirconia nanoparticles.

Surface-modified zirconia nanoparticles

The present invention provides pressure-sensitive adhesives having a refractive index of at least 1.50. The pressure-sensitive adhesives comprise at least one monomer containing a substituted or an unsubstituted biphenyl group.

High refractive index pressure-sensitive adhesives

An adhesive tape that is stretch releasable, articles that contain the adhesive tape, and uses of the adhesive tape are disclosed. The adhesive tapes include a backing layer that is adjacent to at least one pressure-sensitive adhesive layer. The backing layer typically is optically clear and includes a poly(alkylene)copolymer. The pressure-sensitive adhesive layer is a silicone-based adhesive composition. In many embodiments, the adhesive tape is optically clear.

An adhesive article is described that is debondable from substrates or adherends with the application of heat.

Debondable adhesive article

Methods of forming hybrid aerogels are described. The methods include forming a hybrid aerogel from a metal oxide precursor and a branched telechelic copolymer, e.g., co-hydrolyzing and co-condensing the metal oxide precursor and the branched telechelic copolymer. Aerogels and aerogel articles, including hydrophobic aerogels and hydrophobic aerogel articles are also described.
