Primary Use
Solvent for coatings and adhesives
2-Hexanone, also known as methyl n-butyl ketone, is a clear, colorless liquid with a sharp odor that was historically used as a solvent for coatings, adhesives, inks, and waxes. It is no longer produced or used in the United States due to harmful health effects, though it may still be encountered as a byproduct of industrial processes such as wood pulping and coal gasification.
