SURFACE COATINGS AND METHODS
Provided herein include methods and compositions pertaining to coatings, such as paints, for covering a substrate. In some aspects and embodiments the coatings may include a heat reflective metal oxide pigment that, applied to an external surface of a building (or is applied on a substrate used for an external surface of a building such as an architectural metal panel, EIFS, as a stucco top coat or as a top coat for roofing tiles) reduces the energy consumption in the building. In other aspects and embodiments, provided are textured coatings having a texturing material; for example, methods and compositions are provided pertaining to textured coatings that can be applied robotically or in an automated fashion. In various aspects and embodiments, textured coatings are provided that include a texturing material and a heat reflective metal oxide pigment. In some aspects and embodiments heat reflective coatings for concrete or clay tiles and methods of applying such are provided.
1 . A heat reflective coating composition applied to a substrate comprising a heat reflective metal oxide pigment and a fluorinated resin system;
wherein the heat reflective metal oxide pigment comprises one or more pigments selected from the group consisting of a pigment having a corundum-hematite crystal lattice structure, a pigment having a spinel crystal lattice structure and a pigment having a nickel titanate rutile structure.
2 . The composition of claim 1 , wherein the fluorinated resin system is polyvinylidene fluoride (PVDF) or fluoroethylene-alkyl vinyl ether (FEVE).
3 . The composition of claim 1 , wherein the fluorinated resin system is a combination of polyvinylidene fluoride (PVDF) and fluoroethylene-alkyl vinyl ether (FEVE).
4 . The composition of claim 1 , further comprising an acrylic resin.
5 . The composition of claim 4 , wherein the acrylic resin is a quick set resin.
6 . The composition of claim 1 , wherein the heat reflective metal oxide pigment is comprised of an oxide of a metal selected from the group consisting of aluminum, antimony, bismuth, boron, chrome, cobalt, gallium, indium, iron, lanthanum, lithium, magnesium, manganese, molybdenum, neodymium, nickel, niobium, silium, tin, vanadium, and zinc.
7 . The composition of claim 1 , wherein the coating is capable of being applied by a brush, roller, or sprayer.
8 . The composition of claim 1 , wherein the coating is applied in at least one coat with a total dry film thickness of 2-4 mils.
9 . A method of applying a heat reflective coating to a substrate, the method comprising spray applying the coating to the surface of the substrate;
wherein the heat reflective coating comprises a heat reflective metal oxide pigment and a fluorinated resin system; and
wherein the heat reflective metal oxide pigment comprises one or more pigments selected from the group consisting of a pigment having a corundum-hematite crystal lattice structure, a pigment having a spinel crystal lattice structure and a pigment having a nickel titanate rutile structure.
10 . The method of claim 9 , wherein the fluorinated resin system is polyvinylidene fluoride (PVDF) or fluoroethylene-alkyl vinyl ether (FEVE).
11 . The method of claim 9 , wherein the fluorinated resin system is a combination of polyvinylidene fluoride (PVDF) and fluoroethylene-alkyl vinyl ether (FEVE).
12 . The method of claim 9 , further comprising an acrylic resin.
13 . The method of claim 12 , wherein the acrylic resin is a quick set resin.
14 . The method of claim 9 , wherein the heat reflective metal oxide pigment is comprised of an oxide of a metal selected from the group consisting of aluminum, antimony, bismuth, boron, chrome, cobalt, gallium, indium, iron, lanthanum, lithium, magnesium, manganese, molybdenum, neodymium, nickel, niobium, silium, tin, vanadium, and zinc.
15 . The method of claim 9 , wherein the coating is capable of being applied by a brush or roller.
16 . The method of claim 9 , wherein the coating is applied in at least one coat with a total dry film thickness of 2-4 mils.
