Abstract:
1. A coating composition comprising (1) a reactive fluorinated copolymer and (2) an amino resin in a weight ratio of reactive fluorinated copolymer to amino resin of less than 5:95, said amino resin comprising the reaction product of formaldehyde with urea, melamine, benzoguanamine, or acetylguanamine, said reactive fluorinated copolymer having pendant perfluoropolyether groups and pendant groups capable of reacting with the amino resin, wherein said reactive fluorinated copolymer is the reaction product of a monomer mixture comprising (a) a perfluoropolyether monomer of Formula I:  wherein (b) a crosslinking monomer in an amount of at least 5 weight percent based on the weight of the monomer mixture, wherein the crosslinking monomer comprises a hydroxy functional monomer, an optional acid functional monomer, an optional salt of an acid functional monomer, or combinations thereof, wherein the weight percent of the hydroxy functional monomer exceeds the sum of the weight percent of the optional said functional monomer and the weight percent of the optional salt of the acid functional monomer.
