Methyl Propyl Ketone (MPK)

<p>Eastman™ MPK (Methyl n-Propyl Ketone) 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 resins used in formulating coatings with low VOC content. 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.</p> <p><strong>Eastman™ MPK - Substitution for Aerospace Cleaning Applications: </strong> <br>From cleaning to pre-treatment, tests prove Eastman™ MPK is an effective non-HAP solvent alternative to MEK and toluene. With a vapor pressure of 27.8 mm @ 20&deg;C, well below the 45 mm limit allows for compliance to NESHAP (National Emission Standards for Hazardous Air Pollutants) requirements for hand-wipe cleaning operations for aerospace. <a href="http://www.epa.gov/ttnatw01/aerosp/aeroimp.pdf">http://www.epa.gov/ttnatw01/aerosp/aeroimp.pdf.</a></blockquote></p> <p>Eastman™ MPK satisfies the rigorous aerospace performance requirements. It evaporates more slowly than MEK solvent due to its larger molecule. This property allows for much of the solvent to remain on the wipe instead of emitting into the air and extends the useful life of the wipe. </p> <p>*Eastman™ MPK (Methyl n-Propyl Ketone) is not on EPA’s HAP or SARA list, but it does contain <= 10% MIBK, which is on both lists.</p> <p>The chemical substances for this product are listed as Inert Ingredients Permitted for Use in Nonfood Use Pesticide Products under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
