Isobutyl Isobutyrate (CAS 97-85-8)

Isobutyrate Isobutyl IBIB is an economical, moisture-resistant solvent widely used in nitrocellulose paints, coatings based on plastics, and high solids coatings. 

Documemts: COA | MSDS

It is a low volatility solvent with good leveling properties and resistance to blushing. For nitrocellulose, it is an excellent amide-grade effective solvent. The low surface tension of Isobutyrate Isobutyl IBIB plays a positive role in applications requiring improvement on moist substrates. Moreover, in moisture-sensitive coatings such as 2-K polyurethane, its low water solubility makes it an excellent moisture-resistant solvent. The high electrical resistivity of Isobutyrate Isobutyl IBIB also helps to adjust the coating resistivity in the use of electrostatic spraying equipment. Containers of Isobutyrate Isobutyl can explode when heated in a fire.

  • Features and Advantages: Slow evaporation rate (0.4); excellent resistance to blushing and relatively fast touch dry time; medium solvent strength; reduces substrate attack on plastics caused by solvents; lowers VOCs; can be used in high humidity environments; low surface tension; suitable for use with moisture-sensitive polymers; low water miscibility; minimizes moisture absorption during storage; high electrical resistivity; low-cost ester solvent; not listed as a Hazardous Air Pollutant (HAP); usage not restricted by Chapter III of the Clean Air Act; serves as a slow-drying solvent for NC wood finishes; solvent for high solids coatings; alternative to xylene; more economical solvent for mixed thinners.

  • Precautions for Use of Isobutyrate Isobutyl (IBIB) - Emergency Handling for Leaks: Quickly evacuate personnel from the leak-contaminated area to a safe zone and isolate it, strictly restricting access. Eliminate sources of ignition. Emergency responders are advised to wear self-contained positive pressure respirators and antistatic work clothes. Cut off the source of the leak if possible. Prevent entry into sewers, flood drains, or confined spaces. For small leaks: Absorb with sand, vermiculite, or other
