Abstract
Coating compositions are described that can be used to impart hydrophobicity, oleophobicity, stain resistance, or combinations thereof to various substrates. The coating compositions include an amino resin and a reactive fluorinated copolymer. The reactive fluorinated copolymer has pendant perfluoropolyether groups as well as pendant groups capable of reacting with the amino resin. The pendant perfluoropolyether groups of the reactive fluorinated copolymer have a molecular weight of at least 750 g/mole. Articles and methods of preparing articles using the coating compositions are also described.
