Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
70 words
An improved process for the pyrolytic deposition of a tin oxide coating on a substrate wherein the improvement comprises the use of a composition which is liquid at 24° C. consisting essentially of a methyl tin halide selected from the group consisting of mono methyl tin trichloride, dimethyl tin dichloride and mixtures thereof, and an alky tin trichloride which is liquid at 25° C. to deposit said tin oxide coating.
Claim 2
Dependent Claim
70 words
An improved process for the pyrolytic deposition of a tin oxide coating on a substrate wherein the improvement comprises the use of a composition which is liquid at 24° C. consisting essentially of a methyl tin halide selected from the group consisting of mono methyl tin trichloride, dimethyl tin dichloride and mixtures thereof, and an alky tin trichloride which is liquid at 25° C. to deposit said tin oxide coating.
Claim 3
Dependent Claim
18 words
A process as defined in claim 1 wherein the coating deposited contains ingredients to provide reduced infrared emissivity.
