Coated glass substrate with ultraviolet blocking characteristics and including a rheological modifier
View Patent ↗There is provided a forming a solution by mixing at least a polymeric silane, a solvent, acetone, acetic acid, and a rheological enhancer, wherein the rheological enhancer may comprise an acrylic latex; and agitating the solution. Also provided are methods of using the same in coated articles, and coated articles themselves.
1. A method of making a coated article using a rheologically enhanced ultraviolet-blocking coating solution, the method comprising:
forming a solution by adding and stirring the following ingredients: a first solvent; acetone; an intermediate, wherein the intermediate was formed by serially mixing a first silane, a phenone, a triethlyamine, and a second solvent; a second silane; a color stock, wherein the color stock was formed by mixing a third solvent, acetone, a colorant, and a colloidal silica; acetic acid; water; and a rheological enhancer, wherein the overall solution has a pH of less than 3.9; and
using the solution in forming a coating on a substrate.
2. The method of claim 1 , wherein the rheological enhancer comprises less than 10 wt % of the solution, and wherein the solution is substantially a Newtonian fluid.
3. The method of claim 1 , wherein the rheological enhancer comprises less than 5 wt % of the solution, and wherein the solution is substantially a Newtonian fluid.
4. The method of claim 1 wherein the rheological enhancer comprises between 1 and 2 wt % of the solution, and wherein the solution is substantially a Newtonian fluid.
5. The method of claim 1 , wherein the rheological enhancer comprises an acrylic latex.
6. The method of claim 1 , wherein the solution has a viscosity at 25° C. ranging between 50 and 350 cp.
