What Does Solvent-borne Coating Mean?
A solvent-borne coating is a liquid protective layer that is primarily composed of organic compounds and applied to a material's surface to prevent corrosion. Solvent-borne coatings are typically more resilient than water-borne coatings during the curing of the coating.
A solvent-borne coating may also be known as a solvent-based coating.
Corrosionpedia Explains Solvent-borne Coating
Solvent-borne coatings are preferred for applications in humid environments that don't allow water-borne coatings to cure properly. Solvent-borne coatings cure due to a chemical reaction between oxygen in the atmosphere and the constituents of the solvent-borne coating, and not by the evaporation of water. This makes humidity less of a factor for solvent-borne coatings.
Solvent-borne coatings are considered less environmentally friendly than water-borne coatings due to the volatile organic compounds (VOCs) typically present in solvent-borne coatings. Advances in water-borne coatings are making them an increasingly attractive option as a method of protecting material surfaces. However, solvent-borne coatings are still quite popular in harsh conditions.
