  • Publication number: 20170007464
    Abstract: An antimicrobial pressure-sensitive adhesive (PSA). The PSA system can include an antimicrobial polymer having a plurality of pendant groups. The plurality of pendant groups can include (i) a first pendant group comprising a nonpolar compound, (ii) a second pendant group comprising a quaternary ammonium compound, and (iii) a third pendant group different from the first pendant group or the second pendent group, wherein the third pendant group provides inter-reactivity, such that the antimicrobial polymer can include one or more intermolecular interactions. The antimicrobial polymer can be free of non-ionic hydrophilic moieties. The PSA system can have a glass transition temperature Tg ranging from 0 to 50 degrees C.
