Product Description

Eastman Methyl Isobutyl Ketone (MIBK) is a medium-evaporating solvent. It is an active solvent
for many synthetic resins including cellulosics, vinyl copolymers, acrylics, alkyds, polyesters, and
epoxies. It is very useful in developing high-solids coatings because of its combination of high
solvent activity and low density.

In addition to its use as a solvent for inks, coatings, and adhesives, MIBK is used as an extraction
agent in the dewaxing and deoiling of petroleum products. It is also a useful component in
germicides, fungicides, and electroplating solutions, and as a denaturant in many ethanol
formulations.

Eastman MIBK is an Eastman Performance Solvent.
