Abstract
Coating solutions comprising a) a solvent, b) inorganic particles dispersed substantially uniformly in the solution, c) an inorganic surface modifier dispersed substantially uniformly in the solution, and d) an organic cross-linker dispersed substantially uniformly in the solution. The inorganic surface modifier comprises from about 1 to about 30 weight percent of b) and c). Together, b) and c) comprise from about 30 weight percent to about 75 weight percent of b), c), and d). Solutions of the present invention can be applied to a variety of substrates to produce coatings that are highly abrasion-resistant. Coatings of the present inventions also exhibit good oxygen and water vapor barrier properties. Solutions of the present invention can also be utilized to produce three-dimensional objects.
