Coatings are products used to protect a surface and/or enhance its appearance. Architectural coatings are applied to commercial and residential buildings. They protect a building from moisture, UV radiation, and microbes. Paints, primers, lacquers, varnishes, and stains are some of the primary types of architectural coating products. These are formulated using resins such as acrylic, alkyds, polyester, and polyurethane. The market can be broadly classified into two major types of coating technologies: solvent-borne and water-borne.
