Methyl Ethyl Ketone
CAS 78-93-3 · C4H8O · HS 2914.12
Methyl ethyl ketone (MEK, 2-butanone, CAS 78-93-3) is a low-boiling, fast-evaporating ketone with strong solvency for nitrocellulose, acrylics, vinyls, epoxies and polyurethanes. Its combination of high solvency and low viscosity makes it difficult to replace in high-solids coatings, and it is a standard reference in formulations requiring controlled evaporation. MEK is used in coatings, adhesives, printing inks, magnetic tape binders, lube-oil dewaxing and as a chemical intermediate. It is flammable and must be handled with grounded equipment; buyers compare purity, water content, acidity and distillation range.
