Abstract: The disclosed adhesive medical article has a backing layer having a first major surface and a second major surface opposite to the first major surface. The backing layer has a central portion and an outer circumferential portion. The article further has a pressure sensitive adhesive pattern coating applied onto at least part of the first major surface of the backing layer in such a way as to form a plurality of adhesive coated and adhesive uncoated areas of the backing layer. The adhesive uncoated areas comprise a central collection portion and at least one longitudinal extension radiating from the central collection portion towards the outer circumferential portion of the backing layer.

Abstract: Siloxane-based gel adhesives with improved shear holding power are prepared from curable compositions. The curable compositions include a siloxane fluid with a viscosity of at least 1,000,000 centiPoise, a siloxane-(meth)acrylate co-polymer, and siloxane tackifying resin. The curable compositions can contain an initiator or can be cured by e-beam radiation without an initiator. The siloxane-(meth)acrylate copolymer is the reaction product of a reaction mixture of an ethylenically unsaturated siloxane-containing macromer, an alkyl (meth)acrylate monomer; optionally a reinforcing monomer, and an initiator.

Abstract: Siloxane-based gel compositions are prepared from room temperature condensation curable mixtures that include 0.5-45% by weight silicone resin with at least two hydroxyl groups, 99.5-55% by weight of at least one silanol-terminated siloxane fluid, and a co-curable compound with an amino group. The siloxane-based gel compositions can be used as adhesives or sealants in medical articles.

Abstract: The present disclosure provides an adhesive article comprising a foam layer having first and second major sides and a pressure sensitive adhesive layer associated with at least one of the major sides for the foam layer, said pressure sensitive adhesive layer comprising a cross-linked rubber and wherein the foam layer comprises an acrylic polymer obtainable by polymerization a polymerizable composition comprising one or more alkyl acrylates having an average of 3 to 14 carbon atoms in the alkyl groups, one or more polar monomers and one or more multi-functional monomers having at least two free radical polymerizable groups.
