A coating is a very thin layer placed on top of a BSDF. Because coatings are so thin, they produce an effect called thin film interference, which breaks up the light and can cause a rainbow-like pattern. Think for example of spilling a drop of oil on a surface of water. The very thin layer of oil will create interference patterns on the water. Coatings can also be used to create rough materials with a clear coating. For example, a glossy white plastic can be made combining a diffuse BSDF with a coating.

A coating over a white diffuse surface.

A coating alone (disabling the BSDF) can be used to recreate a bubble.

The main property of a coating is its thickness. The thickness is specified in nanometers (nm). Thickness can be specified by a numerical value or through a weight map. To avoid interference coloring, you should use higher thickness values such as 1 mm (1000000 nm).

Only one coating is allowed per BSDF. You can make a material using just a coating and no BSDF, for example to create a bubble material. To do this, add a coating, right-clicking on the BSDF component > Add Coating, and then simply hide the BSDF clicking in the visibility column in the layer list to disable it.
