Abstract
Described herein is a coating composition suitable for application to a building panel. The coating composition comprises inorganic pigment, liquid carrier, and a humectant comprising a first ester-containing compound. The liquid carrier may be present in an amount ranging from about 10 wt. % to about 30 wt. % based on the total weight of the coating composition. Described herein are also building panels coated with the coating composition and methods of their production.
Claims20
A building system comprising:
- a first building panel positioned adjacent to a second building panel, and a seam formed between the first and second building panels;
- a seam-filling material applied to the seam;
- a coating applied to the first and second building panels and the seam-filling material, the coating comprising:
- a binder having a pH of at least about 7.0 and a Tg of at least 20° C.;
- a pigment;
- and
- a viscosity modifier;
- wherein the pigment and the binder are present in a weight ratio of at least about 5:1;
- wherein the viscosity modifier comprises a humectant and a dispersant;
- and
- wherein the humectant and the dispersant are present in a weight ratio ranging from about 1:1 to about 4:1;
- and
- wherein the pigment comprises titanium dioxide, calcium carbonate, alumina trihydrate, and diatomaceous earth.
