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

Methyl isobutyl ketone (MIBK) is a colorless, volatile liquid with the chemical formula C₆H₁₂O, used in various industrial and chemical applications. It is primarily employed as a solvent in the production of coatings, adhesives, and inks, and as a chemical intermediate in organic synthesis. MIBK is also used in the formulation of cleaning agents and paint strippers. Despite its utility, MIBK is highly flammable and poses significant health risks if inhaled, ingested, or absorbed through the skin. Proper handling, storage, and stringent safety measures, including the use of personal protective equipment and adequate ventilation, are essential to minimize risks and ensure safe usage.
