MEK (methyl ethyl ketone)Edit
Description: MEK (methyl ethyl ketone), also known as butanone, is a manufactured organic chemical. It is a colorless liquid with a sharp, sweet odor. Like Acetone , MEK is a ketone, and has many similarities. It dissolves many substances, and is used as a solvent for gums, resins, cellulose acetate and Nitrocellulose . MEK is listed as a Table II precursor under the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances.
Hazards: MEK is very volatile and flammable. MEK vapour is heavier than air, and spreads over the ground. Only work with MEK outside or in a well ventilated area. The known health effects to people from exposure to MEK are slight irritation of the nose, throat, skin, and eyes. There are no known cases of any humans dying from breathing MEK alone. Other than minor irritation, it's basically harmless.
Sources: MEK can usually be bought at any paint store or hardware store. Making MEK at home is very impractical and unnecessary as it can be bought just about anywhere at low cost.
