  • Patent number: 10369247
    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.

  • Patent number: 10370571
    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.

  • Publication number: 20190085222
    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.

  • Publication number: 20160193452
    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.
