Sealing Composition
First Claim
1. A method of treating a substrate comprising:
- contacting at least a portion of the substrate surface with a sealing composition comprising a lithium cation;
wherein the sealing composition is applied to provide a layer of the dried sealing composition having a thickness of 5 nm to 550 nm.

Abstract
Disclosed is a method of treating a substrate. The surface is contacted with a sealing composition comprising a lithium cation; and optionally, with conversion composition comprising a cation of a lanthanide, a Group IIIB, and/or a Group IVB metal. The conversion composition is applied to provide a film on the substrate surface resulting in a level of the lanthanide, Group IIIB metal, and/or Group IV metal thereon of at least 100 counts greater than on a surface of a substrate that does not have the film thereon as measured by X-ray fluorescence (measured using X-Met 7500, Oxford Instruments; operating parameters 60 second timed assay, 15 Kv, 45 μA, filter 3, T(p)=1.5 μs for lanthanides, Group IIIB metals, and Group IVB metals except zirconium; operating parameters 60 second timed assay, 40 Kv, 10 μA, filter 4, T(p)=1.5 μs for zirconium). A substrate obtainable by the methods also is disclosed.
