How thick are most common surface-coating films?

For most common applications, surface-coating films typically range in thickness from 0.5 to 500 micrometres (0.0005 to 0.5 millimetres, or 0.00002 to 0.02 inches).1

These films are formed through processes such as the evaporation of solvents, the cross-linking of polymer precursors, or the coalescence of small particles. Once applied to a substrate and cured, these materials create a functional and often decorative thin film designed to protect surfaces from environmental damage.12
