Transparent matte anti-stain corrosion-resistant surface coating and colored anti-stain corrosion-resistant surface coating for direct ambient temperature moisture-cured topcoat applications

A transparent matte anti-stain and corrosion-resistant surface coating, formable as a topcoat at ambient humidity, comprising:

• a fluorinated modified polysilazane copolymer, wherein the fluorinated modified polysilazane copolymer is present in an amount of 5% to 80% by weight, and wherein the fluorinated modified polysilazane copolymer comprises a fluorinated compound copolymerized with a siloxane and a polysilazane, wherein the fluorinated compound is present in an amount of 10% to 30% by weight, the siloxane is present in an amount of 20% to 30% by weight, and the polysilazane is present in an amount of 40% to 70% by weight;
• wherein the fluorinated compound copolymerized with the siloxane includes poly-heptadecafluorodecyl-methylsiloxane, poly-nonafluorohexyl-siloxane, poly-methyl-trifluoropropyl-siloxane, polydimethylsiloxane, hexafluoropropylene oxide, perfluoropolyether sulfonic acid, perfluoromethyl vinyl ether, polytetrafluoroethylene perfluoromethyl vinyl ether, perfluoropropyl vinyl ether, perfluorosulfonyl vinyl ether, hexafluoroisobutylene, perfluoroethyl vinyl ether, or hexafluoropropylene oxide trimer vinyl ether;
• and wherein the siloxane includes polydimethylsiloxane, methylsiloxane resin, cyclopentasiloxane, phenyltrimethylpolysiloxane, amino-terminated polydimethylsiloxane, or cyclic polydimethylsiloxane.
