Diisobutyl Ketone (DIBK) Supplier in Malaysia
- Also known as
- DIBK
- 2,6-Dimethyl-4-Heptanone
- Isovalerone
- Valerone
Diisobutyl ketone supplier in Malaysia for coatings formulators, ink makers, adhesive plants and process buyers. Traded as DIBK and named 2,6-dimethyl-4-heptanone (CAS 108-83-8, C9H18O), it is a clear liquid ketone with nine carbons, and older catalogues still list it as isovalerone or valerone.
Two properties explain almost every purchase. Its solvency for nitrocellulose, acrylics, vinyl copolymers and epoxy binders is strong enough to keep a heavy resin load fluid at low solvent content, and its very low water solubility keeps it out of the aqueous phase in extraction work and away from moisture haze in a drying film.
Grades separate on purity and water content rather than form: industrial material for general finishes, adhesive cements and process duty, coating and ink grade bought against colour and evaporation limits, and high-purity liquid for extraction circuits and controlled reactions. High-solids and baking coatings, coil finishes, refinish spray blends, metal recovery and resin removal are the usual destinations.
Send the grade, target specification, resin system or process, volume and delivery location with your enquiry. Pack format, documentation, availability and timing are confirmed with the quotation.

Diisobutyl Ketone grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Industrial grade diisobutyl ketone | clear, colourless liquid | industrial solvent specification | Everyday tail-solvent duty in industrial finishes, adhesive cements and process work where the buyer needs the slow ketone behaviour but does not hold colour or trace impurities to a narrow window. | Liquid pack formats such as drum or IBC, agreed with the quotation. |
| High-purity diisobutyl ketone | clear, colourless liquid | high-purity specification | Extraction circuits, reaction media and controlled process steps that carry the solvent forward, where dissolved water or a trace carbonyl impurity would shift yield or product quality. | Drum or IBC liquid supply, with the format settled at quotation. |
| Coating and ink grade diisobutyl ketone | clear, colourless liquid | coating or ink solvent specification | High-solids industrial and refinish coatings, coil finishes and screen or gravure inks bought against a colour, water and evaporation specification set by the formulation. | Drum, IBC or tank liquid formats, confirmed with the quotation. |

Diisobutyl Ketone applications
Safety and handling
Store in closed containers in a cool, well-ventilated area separated from heat, ignition sources and oxidising materials. Handle it as a combustible organic solvent with adequate ventilation, and work to the safety information supplied with the quoted grade. Supply is subject to applicable requirements.
Common questions about diisobutyl ketone
Is diisobutyl ketone the same as DIBK?
Yes. DIBK is the working abbreviation for diisobutyl ketone, written systematically as 2,6-dimethyl-4-heptanone and listed in older catalogues as isovalerone or valerone. Any of those names with a grade and volume is enough to open an enquiry.
How does diisobutyl ketone compare with the shorter ketone solvents?
It evaporates more slowly, so it stays in the film after the lighter ketones have gone. Formulators reach for it when a faster solvent dries the surface before the coating has levelled. Those lighter ketones are separate products with their own specifications and enquiries.
Is diisobutyl ketone the same as diisobutyl phthalate, diisobutylene or methyl isobutyl carbinol?
No. Those three sit near it in supplier catalogues and are frequently mixed up, but a phthalate ester, an olefin and an alcohol behave nothing like a C9 ketone in a formulation. Each is a different product, so quote the one you actually need by name.
Does diisobutyl ketone dissolve in water?
Barely. It has very low water solubility and separates from an aqueous phase rather than mixing with it, which is what makes it useful in extraction duty and in coating systems where dissolved water would cause haze or blushing.
Which resins does diisobutyl ketone handle?
It has strong solvency for nitrocellulose, acrylics, vinyl copolymers, epoxies and many alkyd and polyester binders, which is why it earns a place in high-solids systems where there is little solvent available to keep a heavy resin load fluid. Confirm compatibility with the resin supplier for the exact formulation.
What should a diisobutyl ketone enquiry include?
Include the grade, any purity, colour or water limits, the resin system or process it feeds, the volume and the delivery point. Note documentation needs and the schedule you are working to so the quotation covers everything in one round.
