Methyl Isobutyl Ketone (MIBK), with the chemical formula C₆H₁₂O, is a clear, colorless liquid with a mild, sweet odor. It is a moderately volatile solvent widely used in paints and coatings, industrial cleaning agents, adhesives, and rubber processing. MIBK offers excellent solvency for resins, oils, and gums, and it evaporates slower than acetone and MEK, making it ideal where extended working time is beneficial.
