Abstract
Described herein is a coated building panel having a body and a surface coating atop the body, the surface coating comprising inorganic pigment and a polymeric dispersant comprising a polymer backbone and pendant side chains extending from the polymer backbone; wherein the surface coating comprises a liquid carrier in an amount less than about 1 wt. % based on the total weight of the surface coating.
Claims20
A coated building panel comprising:
- a body comprising an upper surface opposite a lower surface and a side surface extending between the upper surface and the lower surface;
- a thixotropic surface coating applied to the side surface, the thixotropic surface coating comprising:
- a binder having a glass transition temperature less than room temperature;
- and
- pigment in an amount ranging from about 25 wt. % to about 95 wt. % based on the total weight of the thixotropic surface coating, the pigment comprising inorganic pigments;
- an ionic polymeric dispersant;
- wherein the thixotropic surface coating is present in an amount ranging from 7.5 g/m2 to 150 g/m2;
- and
- wherein the binder comprises carboxylated polyvinyl acetate.
