Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
55 words
The method of increasing the deposition rate of a fluorine-doped tin-oxide coating with reduced emissivity on a heated flat-glass substrate which comprises pretreating the substrate with a gaseous treating composition comprising at least 0.1 mol % water, a compound selected from the group consisting of fluorinated carboxylic acids and fluorinated carboxylic anhydrides, and a gas.
Claim 2
Independent Claim
55 words
The method of increasing the deposition rate of a fluorine-doped tin-oxide coating with reduced emissivity on a heated flat-glass substrate which comprises pretreating the substrate with a gaseous treating composition comprising at least 0.1 mol % water, a compound selected from the group consisting of fluorinated carboxylic acids and fluorinated carboxylic anhydrides, and a gas.
Claim 3
Dependent Claim
43 words
The method according to claim 1, wherein the gaseous treating composition comprises from about 0.1 to about 30 mol % water, from about 0.025 to about 5 mol % of the fluorine compound, and from about 65 to about 99.9 mol % air.
