Vapor Pressure in Moist Air - Vapor pressures vs. I would say no. solvent MEK (methyl ethyl ketone). I would wear gloves because soaking your hands in acetone can defat skin tissues and dry your skin out. (3) The chemical formula for methyl ethyl ketone is C4H8O and the molecular weight is 72. Acetone can form explosive mixtures with many different chemicals, so proper research before storing acetone is crucial. I use acetone all the time, but with great care; it will melt many plastics, remove paint (or just ruin the look), dull finishes, destroy video heads, remove the lacquer from coils/transformers and cause shorted windings, etc. This information, based on experience to date, is believed to be reliable. Under the authority of the Federal Advisory Committee Act (FACA) P. or other chemicals should have and use reference books or data sheets that give all relevant information about each chemical. Satisfactory to 72°F (22° C) 2. The dipole moment in methyl ethyl ether is less than in acetone because of the lower polarity of the C-O bond. Just decant the DipSmooth into a glass or metal container and completely dip the part. If we mix acetone and n-heptane, the azeotrope consisting of 9% acetone and 91% heptane boils at 55. Similarly to acetone, methyl ethyl ketone is used to produce its own organic peroxide, MEKP. First of all let’s clear up a few things; Lacquer thinner, acetone, MEK, and enamel or urethane reducers are NOT surface 0 VOC MEK Replacement Results •Substituting the MEK with 0 VOC MEK Sub resulted in a minor 2 –3 KU (Kreb Units) increase in viscosity. E. , rendered undrinkable through contamination with such solvents as methyl alcohol, isopropyl alcohol, acetone, methyl ethyl ketone, methyl isobutyl ketone, etc. With natural and synthetic resins, MEK produces solutions with low viscosity and high solids content. Methyl ethyl ketone Methyl ethyl ketone (MEK) is a colourless, low viscosity liquid with a mild odour similar to that of acetone. Shut off ignition sources and call fire department. They were also exposed to a combination of MEK and MIBK at re: mek vs mekp I won't suggest that MEK (methyl ethyl Ketone) is good for you but in many respects it is not much different in terms of toxicity than any other solvent, including materials such as acetone that we use very casually. Methyl Ethyl Ketone is effective in processes involving resins, cellulose acetate and nitrocellulose coatings and in vinyl films. It may be a stupid question being that everyone uses it, but are there any harmful effects from welding over an area that is cleaned with any of the above mentioned? The other 2 answers where incomplete, missing a molecule. SPS is a national chemical supplier of solvents, thinners, and cleaners for the automotive industry. Slower evaporation time than acetone.
