Isobutyl Isobutyrate (IBIB), identified by CAS Number 97-85-8, is a high-boiling, slow-evaporating ester solvent characterized by its clear, colorless appearance and a distinctively sweet, fruity o…
Superior Flow and Leveling: Its slow evaporation rate facilitates the formation of smooth, high-gloss surfaces by allowing the coating to remain “open” longer.
High Hydrophobicity: It exhibits very low water solubility, which enhances the moisture resistance of cured films and prevents “blushing” in humid environments.
Excellent Resin Solvency: IBIB effectively dissolves a wide range of resins, including nitrocellulose, acrylics, vinyls, and alkyds, ensuring formulation stability.
Surface Tension Reduction: The low surface tension of the liquid aids in substrate wetting and reduces surface defects like orange peel or pinholing.
Cost-Effective Performance: It serves as an economical alternative to more expensive high-boiling glycol ethers or ketones.
Safety Profile: Compared to other esters, it has a lower toxicity profile and is readily biodegradable.
