Abstract: 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.

Abstract: 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.

Abstract: A medical dressing (100) with a dressing body (102) and a flap (104). The flap can include a fixed end (120) coupled to the dressing body, and a free end (122) 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 (116) 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) (115), and the flap can be secured to the dressing body with a securing adhesive (e.g. an acrylate adhesive) (117) that can have a higher adhesion or adhesive strength.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Adhesive compositions and articles containing the adhesive compositions are provided. In some embodiments, the adhesive compositions can be positioned adjacent to biological surfaces such as skin. For example, articles are provided that can be used in wound dressing or that can be used to stabilize and/or affix a medical device or medical instrument to a patient.

Abstract: 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.

Abstract: A stretch releasable adhesive article includes first and second opposed major surfaces and a pull tab, and at least a portion of at least one of the first and second major surfaces is adhesive. The adhesive article has a cross-sectional area—as measured normal to the axis defined by a stretch release force applied to the pull tab during the stretch release process—that has a defined width to thickness ratio, and the adhesive article may have a visible light transmission of at least about 90%, and a haze of no greater than 5%.
