Isopropyl Acetate丨CAS 108-21-4

Isopropyl acetate丨CAS 108-21-4 is a fast-evaporating, low-viscosity solvent with a mild, fruity aroma, making it popular across industrial, commercial, and laboratory settings.

1. Industrial Solvent
a. Coatings and Paints:
Used extensively as a solvent in lacquers, enamels, and coatings, isopropyl acetate provides:
● Rapid evaporation
● Smooth finish without residue
● Reduced viscosity for easier application
It is especially valuable in automotive and industrial coatings, where quick drying and minimal residue are essential.
b. Inks and Printing Industry:
Isopropyl acetate is widely used in flexographic and gravure printing inks because of its fast drying and good solvent power for resins and dyes. It contributes to:
● Crisp printing
● Smudge resistance
● Consistent ink transfer
c. Adhesives and Sealants:
The solvent plays a key role in dissolving polymers used in pressure-sensitive adhesives, rubber cements, and sealants, particularly where a fast set time is needed.

2. Fragrance and Cosmetics
Isopropyl acetate's mild fruity odor and solvent properties make it suitable for use in:
● Perfumes and fragrances
● Aerosol sprays
● Personal care products such as nail polish removers, hair sprays, and aftershaves
Its volatility allows it to evaporate quickly without leaving a residue, making it a preferred choice in fast-drying consumer formulations.

3. Cleaning and Degreasing Agent
Due to its ability to dissolve oils, greases, and waxes, isopropyl acetate is used in:
● Metal degreasing
● Electronic component cleaning
● Optical lens and instrument cleaning
It is also included in formulations for household or industrial cleaners, where rapid drying is important.

4. Laboratory and Pharmaceutical Use
a. Intermediate in Synthesis:
Isopropyl acetate is sometimes used as an intermediate or reagent in organic synthesis, particularly in reactions requiring ester solvents.
b. Extraction and Purification:
It can serve as an extraction solvent in pharmaceutical and chemical laboratories, helping in the purification of compounds or as a carrier solvent in chromatographic processes.

5. Automotive and Aerospace Industry
● Used as a solvent in detailing sprays, automotive waxes, and cleaning agents
● Beneficial for surface preparation prior to painting or adhesive bonding
● In aerospace, it's used in specialty coatings and cleaners due to its rapid evaporation and low residue

1. Fast Evaporation Rate
Ideal for applications where quick drying is crucial, such as paints, coatings, and inks. It minimizes waiting times and production delays.
2. Low Residue
Leaves virtually no residue after evaporation, making it suitable for optics, electronics, and high-purity applications.
3. Mild Odor
Compared to other industrial solvents, it has a pleasant, fruity smell, making it more acceptable in consumer products and indoor applications.
4. Effective Solvency
Isopropyl acetate can dissolve a wide range of resins, oils, and polymers, making it versatile in formulation chemistry.
5. Compatibility and Blending
It is miscible with many common solvents (e.g., ethanol, acetone, hydrocarbons), making it easy to formulate with in custom solvent blends.

Isopropyl acetate丨CAS 108-21-4 is a versatile, fast-drying solvent used across numerous industries including coatings, printing, cosmetics, cleaning, and electronics. Its excellent solvency, quick evaporation, and pleasant scent make it particularly well-suited for both industrial-scale formulations and consumer products. Thanks to its performance and ease of formulation, it remains a staple solvent in modern manufacturing and product development.
