Product Description

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.

Eastman MPK - Substitution for Aerospace Cleaning Applications:
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 @ 20oC, 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. http://www.epa.gov/ttnatw01/aerosp/aeroimp.pdf.
Eastman MPK satisfies the rigorous aerospace performance requirements. It is environmentally friendly, evaporating more slowly than alternative solvents, with no significant contribution to ground-level ozone. Refer to Technical Tip TT-20 below for further details on how Eastman MPK can be used in pre-saturated wipes in the aerospace industry.

Eastman MPK is an Eastman Performance Solvent.
