METHYL ISOBUTYL KETONE Chemical compatibility with O-rings, rubbers, & plastics

Methyl isobutyl ketone, commonly abbreviated as MIBK and also known as hexone, is a colorless, volatile liquid with the chemical formula C6H12O widely used as an industrial solvent. It is commonly used in coatings, adhesives, inks, cleaning formulations, and as an intermediate in organic chemical synthesis. This ketone solvent is highly flammable and may present health risks through inhalation, ingestion, or skin contact. In systems containing MIBK, O-rings, rubber seals, gaskets, and plastic components should be evaluated for chemical compatibility, as ketone solvents can affect certain rubber materials. Proper handling, storage, ventilation, and protective practices are essential.
