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 1 to 30 weight percent of b) and c). Together, b) and c) comprise from 30 weight percent to 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.

L'invention concerne des solutions de revêtement contenant a) un solvant, b) des particules inorganiques dispersées de manière sensiblement uniforme dans la solution, c) un modificateur de surface inorganique dispersé de manière sensiblement uniforme dans la solution, et d) un agent de réticulation organique dispersé de manière sensiblement uniforme dans la solution. Le modificateur de surface inorganique comprend entre 1 et 30 % en poids de b) et c). Ensemble, b) et c) comprennent entre 30 et 75 % en poids de b), c), et d). Les solutions de la présente invention peuvent être appliquées sur une variété de substrats de manière à former des revêtements hautement résistant à l'abrasion. Les revêtements de la présente invention présentent également des propriétés barrières élevées contre la vapeur d'eau et l'oxygène. Les solutions de la présente invention peuvent également être utilisées pour fabriquer des objets tridimensionnels.
