Methyl Isobutyl Ketone (MIBK)

Description

What is Methyl Isobutyl Ketone (MIBK)?

Methyl Isobutyl Ketone (MIBK), also known as 4-methylpentan-2-one, is a clear, colorless liquid organic solvent with a mild, sweet odor. It is widely valued in various industries for its excellent solvency power, moderate evaporation rate, and compatibility with a range of resins. MIBK is commonly produced through a multi-step process from acetone and plays a critical role in the manufacture of coatings, rubber chemicals, and industrial cleaners.

Chemex Chemicals supplies high-purity MIBK that meets stringent industrial standards, making it ideal for both specialized and large-scale applications.

Key Applications of Methyl Isobutyl Ketone (MIBK):

Paints, Coatings & Lacquers

MIBK is a strong solvent for nitrocellulose, acrylics, polyesters, alkyds, and epoxies, making it ideal for high-solids coating formulations. It helps in reducing viscosity and improving film formation.

Rubber Processing

Used in the synthesis of 6PPD (an antiozonant), MIBK plays a vital role in tire manufacturing and rubber applications to prevent cracking from ozone exposure.

Metal Extraction & Purification

Its selective solvency properties make MIBK suitable for use as an extraction solvent in separating and purifying rare metals, such as uranium and other precious metals.

Adhesives and Inks

Thanks to its effective solvency and fast drying time, MIBK is widely used in the production of printing inks, adhesives, and industrial cleaners.

Textile & Leather Finishes

MIBK enhances the performance of textile and leather treatment chemicals, offering even penetration and quick drying.

Features & Benefits of MIBK:

• High Solvency Power – Dissolves a wide range of resins and polymers

• Medium Evaporation Rate – Ideal balance for controlled drying

• High Purity (99.57%) – Ensures performance and consistency
