Coatings may be applied as liquids, gases or solids e.g. powder coatings. Normally 4 key kinds of ingredient are used for coatings. 1)Binders/Film forming materials/polymers. 2) Additives. 3)Pigments/Toners/Fillers/. 4) Solvents including water. |
| These coatings are applied in a liquid state, but dry to leave a solid finish. Liquid coatings comprise a liquid carrier and solids, which are the components left once the coating is dried. There are numerous types of liquid coatings, solvent-based coatings, water-based coatings, high solid liquid coatings. |
| These coatings are applied in a fine powder state. They are based on polymer resin systems, combined with curatives, pigments, leveling agents, flow modifiers, and other additives. These ingredients are melt mixed, cooled, and ground into a uniform powder similar to baking flour. A process called electrostatic spray deposition (ESD) is typically used to achieve the application of the powder coating to a substrate. |
