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

Methyl isobutyl ketone (MIBK), also known as hexone, is an organic compound with the formula C6H12O. It is a colorless, flammable liquid with a distinctive ketone odor. MIBK is widely used as a solvent in the production of paints, varnishes, coatings, and adhesives. It is also employed in the extraction of precious metals, as a chemical intermediate, and in the manufacture of rubber chemicals. MIBK is known for its excellent solvency properties, making it effective in dissolving a wide range of resins and polymers. Handling MIBK requires caution as it can cause skin, eye, and respiratory irritation. Prolonged exposure may result in more severe health effects, including liver and kidney damage. Proper storage and handling procedures, including the use of personal protective equipment and good ventilation, are essential to prevent exposure. MIBK's versatility and widespread use underscore its importance as a valuable industrial solvent.
