Diisobutyl ketone

Diisobutyl ketone (CAS 108-83-8), also known as DIBK or Valerone, is a slow-evaporating ketone solvent used across coatings, adhesives, and flavor applications.

Its controlled evaporation rate makes it a preferred carrier in formulations where extended open time or gradual release is commercially valuable for industrial and specialty chemical processes.

In coatings and lacquers, DIBK functions as a high-boiling solvent that improves flow and leveling in nitrocellulose and acrylic systems, reducing surface defects in the final film.

Adhesive formulators use it to control viscosity and working time in contact cement and pressure-sensitive adhesive systems. In the flavor industry, it is approved under FEMA 3537.

As a flavoring agent, it contributes fruity, sweet notes to food and beverage products. Personal care formulators incorporate it as a solvent carrier in nail care products and aerosol formulations.

It is highly valued where compatibility with resins and slow evaporation are required. Diisobutyl ketone is supplied as a clear liquid in standard industrial drum and IBC quantities.

Technical grade is the most common supply form for solvent applications, while flavor-grade material is available for food and cosmetic use. Buyers should confirm purity specifications.

Grade documentation is essential when sourcing for regulated end-use categories. Ensure all materials meet necessary safety and regulatory requirements for your specific application needs.
