Methyl Ethyl Ketone, abbreviated as MEK and also known as Butanone, is a chemical compound characterized as a colorless, flammable, and easily evaporable liquid with a sharp and sweet odor. It's a polar solvent, soluble in water, and commonly used in the production of adhesives, paints, inks, coatings, and as a cleaning agent in various industries. But did you know? Not all rubber sheets are suitable for use with Methyl Ethyl Ketone (MEK), even those like Viton (VITON/FKM) rubber sheets, known for their chemical resistance.
