COATINGS

LIQUID COATINGS POWDER COATINGS

The variety of coatings available for today’s surfaces is extensive. As its name implies, a coating is a covering applied to the surface of an object, for decorative and/or functional uses. Coatings can be applied to a substrate as solids, liquids or gases. Coatings also come in other forms, including decorative foils and lightweight papers.

Many industrial coating processes involve the application of a thin film of the coating material onto a substrate, finishing the substrate for residential or commercial uses. If the substrate being used starts and finishes the process wound onto a roll, the process is called “roll-to-roll” or “web-based” coating. This roll of this substrate is called a “web.”

Coatings including paint and lacquer can offer the added advantage of both protecting the substrate while being decorative, while other functional coatings may be applied to improve the surface properties of the substrate, such as wear, water or corrosion resistance and adhesion. Other coatings can add a completely new property, such as magnetism or electrical conductivity, to the substrate.
