It is also used as a component of synthetic flavouring substances and adjuvants, and as a component of adhesives that are present in articles intended for use in packaging, transporting or holding food. Methyl Isobutyl Ketone is also considered to be an excellent solvent for resins used in the production of surface coating and is widely used in rubber chemicals for the production of tyres. Methyl isobutyl ketone is also used as a solvent in paint and lacquers.
