Eastman™ MPK (Methyl Propyl Ketone), UHP (Ultra High Purity), is a medium evaporating, urethane grade solvent. It is an active solvent for most synthetic resins including acrylics, polyesters, cellulosics, epoxies, vinyls, and alkyds. Its high solvency, low density, and medium evaporation rate make it attractive as a letdown solvent for high-solids air-dry resins used in low VOC alkyd and polyester/urethane coatings. It is used in gravure printing inks and also provides excellent performance for a wide range of cleaning and surface preparation applications for the transportation industry. Eastman™ MPK, UHP - Substitution for Aerospace Cleaning Applications From cleaning to pre-treatment, tests prove Eastman™ MPK, UHP is an effective non-HAP solvent alternative to MEK and toluene. Eastman™ MPK, UHP satisfies the rigorous aerospace performance requirements. It is environmentally friendly, evaporating more slowly than alternative solvents, thereby reducing total solvent usage.
