发明名称 Coating compositions containing a highly fluorinated polymeric additive
摘要 A coating composition that forms a finish that is soil resistant and easily cleaned having a binder of (A) an acrylic polymer of polymerized hydroxyl containing monomers of hydroxy alkyl (meth)acrylate having 1-4 carbon atoms in the alkyl group, and polymerized monomers from the group of alkyl (meth)acrylates having 1-18 carbon atoms in the alkyl group, styrene or any mixtures of the above and the acrylic polymer having a weight average molecular weight of about 2,000-20,000 determined by gel permeation chromatography, (B) an acrylic polymeric additive of polymerized monomers from the group of alkyl (meth)acrylates having 1-18 carbon atoms in the alkyl groups, styrene or any mixtures of the above, and polymerized fluoro alkyl containing monomer represented by the formula where R is selected from the group of hydrogen or an alkyl group having 1-2 carbon atoms, X is a divalent radical and Rf is a fluoro alkyl containing group having 4-20 carbon atoms and the acrylic polymer having a weight average molecular weight of about 1,000-15,000 determined by gel permeation chromatography, and (C) an organic crosslinking agent; and where a cured layer of the coating of the composition has a combination of advancing water contact angle of at least 100 DEG and a hexadecane advancing contact angle of at least 40 DEG . Articles coated with the composition also are part of this invention.
