Features Of Dow Diisobutyl Ketone DIBK

  1. Low volatility with high boiling point (194–196 °C), enabling extended open time in coatings and inks.

  2. Excellent solvency for cellulose esters, acrylic resins, and epoxy systems without excessive odor or toxicity.

  3. High flash point (70 °C, closed cup) supporting safer handling and transportation under standard chemical regulations.

  4. Low water solubility and immiscibility with water, minimizing formulation instability in moisture-sensitive applications.

  5. Good compatibility with common hydrocarbon and oxygenated solvents for flexible blend design.

Typical Applications Of Dow Diisobutyl Ketone DIBK

  1. High-solids industrial coatings for automotive refinish and metal furniture.

  2. Gravure and flexographic printing inks requiring balanced evaporation rate and film formation.

  3. Adhesives and sealants based on nitrocellulose, chlorinated rubber, or acrylic polymers.

  4. Specialty cleaning formulations for precision degreasing of electronic components and optical parts.

  5. Chemical intermediate in synthesis of pharmaceuticals, agrochemicals, and specialty esters.
