A corrosion study conducted by NACE International, now AMPP, shows that 50% of all corrosion costs are preventable – with roughly 85% of these specific to protective coatings.
Protective coatings, including paints, are thin layers of solid material applied to a substrate with the coating acting as a barrier to inhibit or prevent corrosion, wear, or exposure to water. Each liquid, liquefiable, or mastic composition is converted into a solid protective, decorative, or functional adherent film after application to a surface. Coatings may be sprayed on, welded on, plated on, or applied using hand tools depending on the coating surface, environment, and application goals.
Materials commonly used in organic coatings are epoxies, polyurethanes, or other polymers while materials typically found in inorganic metallic coatings include zinc, aluminum, and chromium.
After the preparation of a surface, coatings are applied in a 3-step process: first, a primer, then a full coating, followed by a sealant.
