2-(2-Ethoxyethoxy)ethyl acetate

The application fields of diethylene glycol ethyl ether acetate (CAS No.: 112-15-2, also known as carbitol acetate) are as follows:

1. Coatings and Paints Industry

• Solvent and Film Former:

• Acts as a high-boiling solvent in water-based and solvent-based coatings (e.g., acrylic, alkyd, and epoxy resins).

• Improves paint flow, leveling, and adhesion, while reducing brush marks and surface defects.

• Printing Inks:

• Used in flexographic, gravure, and screen printing inks to enhance pigment dispersion and drying properties.

2. Textile and Leather Processing

• Textile Auxiliaries:

• Solvent for textile dyes and finishing agents (e.g., reactive dyes, softeners), ensuring uniform coloration and fabric handfeel.

• Leather Treatment:

• Plasticizer and coating solvent in leather finishing to improve flexibility and water resistance.

3. Adhesives and Sealants

• Formulation Aid:

• Enhances the solubility of polymers (e.g., polyvinyl acetate, polyurethane) in adhesives, improving bond strength and flexibility.

• Construction Sealants:

• Used in low-odor, high-performance sealants for building applications.

4. Electronics and Semiconductors

• Cleaning Solvent:

• Removes flux residues, oils, and contaminants from electronic components during manufacturing (e.g., PCBs, semiconductors).

• Lithography Processes:

• Solvent in photoresist formulations for microfabrication due to its high purity and low volatility.

5. Industrial Cleaning and Degreasing

• Heavy-Duty Cleaners:

• Effective in removing grease, wax, and resin deposits in metalworking, automotive, and aerospace industries.

• Aerosol Cleaners:

• Component of sprayable cleaning solutions for precision machinery and equipment.

6. Cosmetics and Personal Care

• Solvent and Emulsifier:

• Used in nail polishes, hair sprays, and skin creams to dissolve active ingredients and improve product stability.

• Fragrance Formulations:

• Carrier for essential oils and fragrances in perfumes and colognes.

7. Agricultural Chemicals

• Pesticide Formulations:

• Solvent for oil-soluble pesticides (e.g., herbicides, insecticides), enhancing sprayability and plant absorption.

• Fertilizer Adjuvants:

• Improves the miscibility of liquid fertilizers with water or oil-based systems.

8. Automotive and Aerospace

• Automotive Coatings:

• Used in OEM and refinish automotive paints for better gloss and weather resistance.

• Aerospace Fluids:

• Component of hydraulic fluid additives and aircraft surface cleaners.

9. Pharmaceutical Industry

• Solvent for Pharmaceutical Coatings:

• Used in enteric coatings for tablets and capsules to control drug release.

• Topical Preparations:

• Solvent in creams, lotions, and ointments for improved drug delivery.

Key Properties Driving Its Use:

• High boiling point (201–202°C) and low volatility for slow-evaporating systems.

• Excellent solvency for both polar and nonpolar materials.

• Low toxicity and moderate evaporation rate, making it suitable for industrial and consumer applications.
