Methyl isobutyl ketone (MIBK)

MIBK is used as a chemical intermediate, a solvent for manufacturing paints, rubbers, pharmaceuticals, other chemicals, and industrial cleaners. It is used in the semiconductor industry. MIBK is very efficient at dissolving resins used in paints, inks, lacquers, and other types of surface coatings. Synonyms for MIBK are hexone, isobutyl methyl ketone, and isohexanone. MIBK is a Food and Drug Administration (FDA)-approved indirect food additive for adhesives, paper and paperboard, and polymers.
