Methyl Isobutyl Ketone (MIBK)
CAS Number: 108-10-1
Methyl isobutyl ketone (MIBK, ≥99.0%) is a medium-boiling ketone solvent with excellent solvency for vinyl resins, nitrocellulose, acrylics, and epoxies. Its partial miscibility with water makes it an ideal extraction solvent for metal ions in hydrometallurgy, and its slow evaporation profile benefits high-gloss coatings.
