Description
A protective or decorative layer placed on the surface of another material (substrate). The purpose of applying the coating may be decorative, functional, or both. Coatings may be applied as liquids, gases or solids e.g. powder coatings. Examples of the types of materials are used for coatings include:
- Fabrics, Metals, Paints, Varnishes and Polymer films.
The primary purpose for most coatings is protection. Often coatings are used to achieve multiple goals. For example, coatings can be formulated to:
- seal a surface, form a barrier, change color, maintain surface appearance, be anti-corrosive, be anti-reflective, decrease friction, increase wearability, minimize light transmission, provide adhesion, prevent adhesion (non-stick), provide flame resistance, and to provide identification.
A major consideration for most coating processes is controlling coating thickness. Methods of achieving this range from a simple brush to expensive precision machinery.
- Application processes include: draping, brushing, rolling, dipping, spraying, baking, shrink-wrapping, vapor deposition, electrostatic deposition, plating, anodizing, printing.
