Over the decades, formulations of paints and coatings have become more and more sophisticated. Today, coatings not only protect and beautify the substrate. They also have functional properties: they are used as anti-skid surfaces, they can insulate or act as an electrical conductor, they can reflect or absorb light, etc. Paints and coatings play an indispensable role in our modern world and cover virtually everything we use from household appliances, buildings, cars, ships, airplanes to computers, microchips or printed circuit boards
