Polyurea coating is a type of coatings, which are applied to improve the performance efficiency of the substrate. It is produced by reacting isocyanate with resin blend that forms a rubber-like substance, which coats the substrate. It is compatible with various substrates such as concrete, metals, wood, and others in a wide range of temperature and humidity. Furthermore, it is eco-friendly and does not contain any volatile organic compounds (VOC). Various conventional coatings are available in the market such as epoxy, vinyl ester, PU, and polychloroprene coating. Polyurea coating provides several advantages over conventional coatings such as fast curing, high coating thickness, and extreme weather resistance to high humidity and low temperatures. Moreover, it impart superior durability, abrasion resistance, corrosion resistance, waterproofing, chemical resistance, decoration, and structural enhancement than conventional coatings. This coating is available in water-based formulations and variety of color and designs. Similar to conventional coatings, polyurea coating requires surface preparation such as sandblasting or priming prior to its application. Technological innovations have led to the availability of antimicrobial agents in polyurea coatings, which prevent the product from degrading.
