A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Methyl isobutyl ketone (CAS 108-10-1), or MIBK, is an aliphatic ketone solvent. It dissolves gums, natural and synthetic resins, nitrocellulose, paints, varnishes, and lacquers, and is used as an extraction solvent for metals and in adhesive and coating manufacture.
Frequently Asked Questions
What is methyl isobutyl ketone used for?
MIBK (CAS 108-10-1) is an aliphatic ketone solvent for paints, varnishes, lacquers, and nitrocellulose; for vinyl, epoxy, acrylic, and natural resins; as an extraction solvent in hydrometallurgy; and in adhesives and printing inks. RawSource supplies it in bulk for coatings and process use.
What is another name for MIBK?
MIBK stands for methyl isobutyl ketone; it is also called 4-methyl-2-pentanone or isobutyl methyl ketone. The CAS number is 108-10-1 and the HS code is 2914.13.
Is MIBK the same as MEK?
No. MIBK is methyl isobutyl ketone (C6H12O, CAS 108-10-1); MEK is methyl ethyl ketone (C4H8O, CAS 78-93-3). MIBK is a larger, higher-boiling ketone with a slower evaporation rate, often chosen for stronger resin solvency in coatings.
How is MIBK shipped and classified for transport?
MIBK is a flammable liquid, UN 1245, and ships under the applicable DOT/IMDG flammable-liquid requirements. RawSource supplies it in drums, totes, and bulk with a CoA and SDS per shipment; see the SDS for GHS classification and handling.
What is the cost of bulk methyl isobutyl ketone?
Bulk MIBK pricing varies with volume, packaging, and freight. Request a bulk quote from RawSource with your target quantity and delivery location for current pricing and lead time.
