Ester Solvent

Definition - What does Ester Solvent mean?

An ester solvent is a chemical substance that is made up of an acid with at least one –OH (hydroxyl) group that has been replaced by an –O–alkyl (alkoxy) group. Ester solvents are often used in corrosion prevention paints.

Corrosionpedia explains Ester Solvent

Ester solvents characteristically have strong hydrogen bonds and polarity. They are able to dissolve a wide range of organic compounds, particularly biological species or environments that may act as corrosion attack facilitators on metallic substrates.

Ester solvents are also used for applications requiring the removal of spilled petroleum products from bodies of water. Ester solvents are non-toxic, non-volatile and biodegradable; thus, they are widely used instead of volatile, highly regulated solvents to clean contaminants from metallic objects.
