Aerospace
Clean surfaces are critical for coating processes used for military and commercial aircraft. The use of hand-wipe cleaners is an effective method for removing soil, oils, adhesives, and other contaminants from aircraft surfaces. With many common solvents, including chlorofluorocarbons (CFCs), being regulated by the Montreal Protocol or the United States Environmental Protection Agency’s (EPA) National Emission Standards for Hazardous Air Pollutants (NESHAP), alternative solvents have been evaluated.
Eastman MPK and Eastman MPK, UHP (ultra high purity), solvents are solvent alternatives to MEK and toluene for cleaning military and commercial aircraft. Eastman MPK solvent satisfies the aerospace surface cleaning performance requirements and is suitable for the cleaning of paint gun equipment. It is environmentally friendly and meets the hand-wipe cleaning solvents’ composition requirements in the EPA’s NESHAP for source categories Aerospace Manufacturing and Rework Facilities. It is slower evaporating than MEK. This feature of Eastman MPK solvent allows for more material to remain in the wipe during cleaning and extends the usable life of the wipe.
MPK (methyl propyl ketone) is not on the EPA’s Hazardous Air Pollutants (HAP) or Superfund Amendments and Reauthorization Act of 1986 (SARA) lists, but it does contain
≤ 10 wt.% MIBK, which is on both lists. Eastman MPK, UHP, contains ≤ 0.1 wt.% MIBK.
Automotive
Eastman oxygenated solvents provide excellent performance in a variety of cleaning formulations for the automotive market. Whether choosing from glycol ethers, ketones, and/or esters, Eastman solvents deliver cleaning efficacy in a variety of automotive cleaners.
