1. An article comprising:
a coating composition comprising a vinyl polymer having a plurality of pendant groups comprising
a first pendant group comprising a cationic component selected from the group consisting of a quaternary amine component, protonated tertiary amine component, and a protonated secondary amine component;
a second pendant group comprising a nonpolar component wherein the second pendant group is selected from the group consisting of linear or branched alkanes, alkaryl, aralkyl, aromatic groups, and combinations thereof; and a third pendant group
a third pendant group comprising a first organosilicon component;
wherein the vinyl polymer does not comprise a pendant group that comprises a carboxylate group; and
a medical device comprising an elastomeric first substrate having a patient-contact first surface and a second surface;
wherein the vinyl polymer is durably adhered to the patient-contact first surface, wherein the composition is free of inorganic filler; and
wherein the coating composition was deposited and cured with an additional free silane present in the coating composition; wherein the additional free silane is a quaternary ammonium silane or protonated tertiary amino silane having at least one straight or branched chain alkyl of 6-22 carbon atoms.
