Di Acetone Alcohol (chemical name: 4-Hydroxy-4-methylpentan-2-one) is a clear, colorless to pale yellow liquid with a mild acetone-like odor. It is a versatile organic solvent and intermediate widely used in the manufacture of coatings, adhesives, inks, and specialty chemicals. Di Acetone Alcohol exhibits excellent solvency for resins, oils, and fats, combined with moderate evaporation rate and low volatility compared to acetone, making it suitable for controlled drying applications. It also serves as a chemical intermediate in synthesis reactions and as a component in solvent blends to optimize performance and drying characteristics.
