Definition - What does Organic Coating mean?
An organic coating is a type of coating whose primary ingredients are derived from either vegetable or animal matter or from compounds rich in carbon. These coatings are primarily used to provide additive type finishes on the materials on which they are applied. Organic coatings can be monolithic (consisting of only one layer) or two or more layers.
Corrosionpedia explains Organic Coating
Organic coatings act as a protective barrier against corrosion and oxidation. These are durable coatings applied to a substrate for their decorative or specific technical properties. Organic coatings depend primarily on their chemical inertness and impermeability. Various types of organic coatings are available for industrial purposes including primers, adhesive cements and topcoats (enamel, varnish and paints).
Organic coatings are easy to apply with the help of brushes, sprays, rollers, dips, or by electrostatic means. Brush application is a slow and lengthy procedure. The coating cures or dries by evaporation or loss of solvent, polymerization and oxidation.
