Abstract
Official abstract text for this publication.
Described herein is a building panel comprising a body having a first major surface opposite a second major surface and a side surface extending therebetween, a coating applied to at least one of the first major surface, the second major surface, or the side surface, the coating comprising a binder, and a pigment composition comprising titanium dioxide, an alkali metal silicate, and a clay; wherein the titanium dioxide is present in an amount ranging from about 3.0 wt. % to about 15.0 wt. % based on the total weight of the pigment composition.
First claim
Opening claim text (preview).
What is claimed is: 1. A coating composition comprising: a liquid carrier; a binder; and a pigment composition comprising: titanium dioxide; an alkali metal silicate; a clay; and one or more alkaline earth metal carbonates comprising magnesium carbonate and calcium carbonate; wherein the one or more alkaline earth metal carbonates is present in an amount ranging from about 60.0 wt. % to about 80.0 wt. % based on the total weight of the pigment composition; and wherein the calcium carbonate and the magnesium carbonate are present in a weight ratio ranging from about 3:1 to about 6:1. 2. The coating composition according to claim 1 , wherein the pigment composition is present in an amount ranging from about 55.0 wt. % to about 80.0 wt. % based on the total weight of the coating composition. 3. The coating composition according to claim 1 , wherein the alkali metal silicate is sodium aluminum silicate. 4. The coating composition according to claim 1 , wherein the binder is a vinyl acetate polymer. 5. The coating composition according to claim 1 , wherein the binder is present in an amount ranging from about 2.0 wt. % to about 8.0 wt. % based on the total weight of the coating composition. 6. The coating composition according to claim 1 , wherein the coating composition has a solids content ranging from about 50% to about 85%. 7. The coating composition according to claim 1 , wherein the liquid carrier comprises water.
