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.
Claims17
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 surface coating atop the upper surface, the surface coating comprising:
- inorganic pigment;
- a binder comprising carboxylated polyvinyl acetate homopolymer;
- and
- an anionic polymeric dispersant comprising a polymer backbone and pendant side chains extending from the polymer backbone;
- wherein anionic groups are located on the terminal ends of the pendant side-chains;
- and
- 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.
