Description
A colorless, stable, low volatility liquid. Butyl lactate is used as a solvent for paints, lacquers, varnishes, oils, dyes, inks, and synthetic resins. It is usually blended with other solvents to slow evaporation and increase drying times. Butyl lactate has also been used as a solvent for Polyvinyl acetate based paints. Toch used small amounts of butyl lactate mixed with turpentine for cleaning paintings (Toch 1931).
Synonyms and Related Terms
