A method of forming a protective coating comprising:
- a) applying a coating composition to a substrate, the coating composition comprising an alkyd resin, laponite clay, and liquid carrier, wherein the alkyd resin and laponite clay are present in a weight ratio of at least 20:1;
- b) curing the alkyd resin and drying off the liquid carrier to form the protective coating atop the building panel, the protective coating having a solids content of at least 99 wt. %.
A method of forming a protective coating comprising:
- a) applying a coating composition to a substrate having a flame-retardant coating applied thereto, wherein the coating composition is applied to the flame-retardant coating atop the substrate, the coating composition comprising an alkyd resin, laponite clay, and liquid carrier;
- b) curing the alkyd resin and drying off the liquid carrier to form the protective coating atop the substrate, the protective coating having a solids content of at least 99 wt. %.
(canceled)
A building panel comprising:
- a substrate;
- a coating applied to the substrate, the coating comprising:
- laponite clay;
- and
- a polymeric composition comprising a cured alkyd resin, the cured alkyd resin and the laponite clay present in a weight ratio of at least 20:1;
- wherein the building panel comprises an exposed surface formed by the coating, and wherein the second coating has a solids content of at least 99%.
