Ketone

Molecular Formula: C4H8O

Structural Formula

CAS No.: 78-93-3

Description

Methyl ethyl ketone, MEK, a low boiling, fast evaporating   solvent is a colorless, stable liquid, partially miscible with water. Methyl   ethyl ketone displays exceptionally good solvency for most resinous materials   including epoxy resins, nitro-cellulose, ethyl cellulose,   cellulose-aceto-butyrate, alkyd, polyester, polyurethane, acrylic resins,   vinyl polymers and copolymers. Also readily dissolved are practically all   synthetic and natural resins commonly employed in the formulation of printing   inks, lacquers, and other types of coatings. In addition, its complete   miscibility with most other solvents as well as alcohols and hydrocarbon   diluents makes methyl ethyl ketone a highly desirable and versatile solvent   in surface coating applications.
