Methylethyl ketone oxime is the organic compound with the formula C 2 H 5 C(NOH)CH 3.This colourless liquid is the oxime derivative of methyl ethyl ketone. MEKO, as it is called in the paint industry, is used to suppress "skinning" of paints: the formation of a skin on paint before it is used.
Gamma-Butyrolactone is used as a chemical solvent and a cleaning agent, [15] for example in paint stripping or for cleaning graffiti. [16] Butyrolactone is a precursor to other chemicals.
