First claim
Opening claim text (preview).
The invention claimed is: 1. A water-repellent coating composition comprising: a coating composition including a silane compound; a solvent; and an adhesion-enhancing additive, wherein the silane compound is one or more selected from the group consisting of: trifluoromethyltrimethoxysilane; trifluoromethyltriethoxysilane; trifluoropropyltrimethoxysilane; trifluoropropyltriethoxysilane; nonafluorobutylethyltrimethoxysilane; nonafluorobutylethyltriethoxysilane; nonafluorohexyltrimethoxysilane; nonafluorohexyltriethoxysilane; heptadecafluorodecyltrimethoxysilane; heptadecafluorodecyltriethoxysilane; heptadecafluorodecyltriisopropylsilane; 3-trimethoxysilylpropylpentadecafluorooctate; 3-triethoxysilylpropylpentadecafluorooctate; 3-trimethoxysilylpropylpentadecafluoroocticamide; 3-triethoxysilylpropylpentadecafluoroocticamide; 2-trimethoxysilylethylpentadecafluorodecylsulfide; 2-triethoxysilylethylpentadecafluorodecylsulfide; pentafluorophenyltrimethoxysilane; pentafluorophenyltriethoxysilane; 4-(perfluorotolyl)trimethoxysilane; 4-(perfluorotolyl)triethoxysilane; dimethoxybis(pentafluorophenyl)silane; diethoxybis(4-pentafluorotolyl)silane; derivatives, and polymers thereof, and wherein the adhesion-enhancing additive includes a phosphoric acid or a phosphoric acid-based compound. 2. The water-repellent coating composition of claim 1 , wherein the adhesion-enhancing additive is included in an amount of 3 parts by weight to 100 parts by weight with respect to 100 parts by weight of the coating composition. 3. The water-repellent coating composition of claim 1 , wherein the solvent is one or more selected from the group consisting of 1,3-bistrifluoromethylbenzene, ethylnonafluorobutylether, ethylnonafluoroisobutylether, perfluorobutylethylether, perfluorohexylmethylether, perfluorocarbons, hydrofluoroethers, and derivatives thereof. 4. The water-repellent coating composition of claim 1 , wherein the water-repellent coating composition has a viscosity of 0.1 cP to 500 cP. 5. The water-repellent coating composition of claim 1 , wherein the coating composition further includes one or more additives selected from the group consisting of antioxidants and leveling agents.
