Description
Methyl isobutyl ketone (CAS 108-10-1), also known as MIBK, MIK, Hexone, or Hexon, is a six-carbon ketone solvent classified under HS code 2914 13 00. It carries no E-code designation and is recognized in flavoring applications under FEMA 2731.
In coatings and adhesives, MIBK dissolves nitrocellulose, vinyl, and epoxy resins at a controlled evaporation rate, reducing blushing in humid conditions. In polymer manufacturing, it functions as a crosslinking agent by reacting with amine groups to form stable methylene bridges. Food and personal care formulators use it as a flavorant and fragrance carrier at regulated trace levels.
MIBK is available in technical and FCC-grade forms, supporting both industrial and food-contact applications. It is fully registered under REACH and supplied in drums and IBC containers. Procurement teams should confirm grade specification against FCC or relevant food safety frameworks prior to sourcing.
