Eastman DIBK Diisobutyl Ketone

Eastman DIBK Diisobutyl Ketone is a high-purity, low-volatility solvent from Eastman’s specialty solvents series—ideal for coatings, inks, and adhesives due to its excellent solvency, slow evaporation rate, and low odor. It offers superior compatibility with resins like acrylics and cellulose derivatives while enhancing flow and leveling without compromising viscosity stability.

Features Of Eastman DIBK Diisobutyl Ketone

  1. Low volatility with high boiling point (179–181 °C), enabling extended open time in coatings and inks.

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

  3. Low water solubility and high flash point (64 °C, closed cup), enhancing handling safety and formulation stability.

  4. Good compatibility with common organic solvents, facilitating easy integration into multi-solvent blends.

  5. High purity (>99.0% minimum) ensures consistent performance and reduced risk of haze or residue in final films.

Typical Applications Of Eastman DIBK Diisobutyl Ketone

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

  2. Gravure and flexographic printing inks requiring controlled evaporation and film clarity.

  3. Solvent-based adhesives and laminating systems where balance of solvency and drying rate is critical.

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

  5. Chemical intermediate carrier in pharmaceutical and agrochemical synthesis processes.
