Claims20
A building panel comprising:
- a substrate comprising a first major surface opposite a second major surface;
- and
- a coating atop at least one of the first major surface or the second major surface, the coating comprising:
- an antimicrobial composition;
- a binder;
- and
- a pigment;
- wherein the antimicrobial composition comprises particles selected from the group consisting of an aluminum silicate, a magnesium silicate, and a mixture thereof, and
- wherein the particles are modified with a quaternary ammonium salt.
A coating composition comprising:
- a liquid carrier;
- an antimicrobial composition;
- a binder;
- and
- a pigment;
- wherein the antimicrobial composition comprises particles selected from the group consisting of an aluminum silicate, a magnesium silicate, and a mixture thereof, and
- wherein the particles are modified with a quaternary ammonium salt.
A method for forming a coated building panel comprising:
- a) applying a coating composition according to a substrate;
- and
- b) drying the coating composition so that substantially all liquid carrier is removed to form the coated building panel, wherein the coating composition comprises:
- a liquid carrier;
- an antimicrobial composition;
- a binder;
- and
- a pigment;
- wherein the antimicrobial composition comprises particles selected from the group consisting of an aluminum silicate, a magnesium silicate, and a mixture thereof, and
- wherein the particles are modified with a quaternary ammonium salt.
