Why Is Ethyl Acetate Solvent Used in Paints? CAS No 141-78-6

Mar 20, 2026 Leave a message

As a fast-evaporating, low-toxicity solvent, ethyl acetate (ETAC/EtOAc) is widely used in the coatings industry to dissolve resins, adjust viscosity, and improve film-forming properties and surface finish. It ensures smooth application and durability in varnishes, enamel paints, and gloss paints, and is also regarded as a "green," biodegradable solvent.
