What is a "coating"?

A coating is a thin layer of material applied to the surface of an object to provide protection, enhance appearance, or improve performance. Coatings can be made from a variety of substances, including varnishes, lacquers, resins, and polymers. They are commonly used in industries such as manufacturing, automotive, construction, and aerospace. Coatings serve several purposes, including protecting surfaces from corrosion, abrasion, and weathering, reducing friction, and providing a barrier against moisture or chemicals. They are applied using various methods, such as spraying, brushing, rolling, or dipping, depending on the specific requirements of the application.
