Floor coating or industrial coating is the protective floor coating system, low maintenance and high resistance used at commercial or industrial premises. An industrial coating is a paint or coating defined by its protective, rather than its aesthetic properties, although it can provide both. The most common use of industrial coatings is for corrosion control of steel structures such as offshore platforms, bridges and underground pipelines. Other functions include in tumescent coatings for fire resistance. The most common polymers used in industrial coatings are polyurethane, epoxy and moisture-cure urethane. Another highly common polymer used in industrial coating is a fluoropolymer. There are many types of industrial coatings including inorganic zinc, phosphate, and Xylan and PVD coatings.
