MASONRY TREATMENT COMPOSTITION
Provided is a masonry treatment composition containing a fluorine-containing polymer, which contains, as essential components, a fluorine-containing monomer having a fluoroalkyl group represented by the formula (a) CH.sub.2C(X)C(O)YZRf, a first hydrophilic monomer represented by formula (b) CH.sub.2CX.sup.11C(O)OROX.sup.12, a second hydrophilic monomer represented by formula (c) CH.sub.2CX.sup.21C(O)O(RO).sub.nX.sup.22 or CH.sub.2CX.sup.31C(O)O(RO).sub.nC(O)CX.sup.32CH.sub.2, and (d) repeating units derived from a monomer having an anion donor and an ethylenic unsaturated double bond. Provided is a treatment composition which can impart outstanding water repellency, oil repellency and anti-fouling properties to a masonry substrate.
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.
