1. Fluorochemical allophanates comprising one or more monovalent fluoroaliphatic radicals having at least three fully fluorinated terminal carbon atoms and one or more allophanate moieties, said radicals and moieties bonded together by first organic linking groups, which may contain hetero atoms, said first linking groups being free of groups with active hydrogen atoms, and where said fluorochemical allophanates contain amino or acid moieties, one or more linked fluoroaliphatic radicals and allophanate moieties are present, and where said fluorochemical allophanates are free of amino and acid moieties, two or more of said linked fluoroaliphatic radicals and allophanate moieties are bonded together by polyvalent second organic linking groups, which may contain hetero atoms;

  • said second linking groups being free of groups with active hydrogen atoms.
