Diethylene glycol butyl ether acetate (DBAC) is a high-boiling-point solvent with extensive applications in industrial fields. Its specific uses are as follows:

? I. Coatings and Inks

1. ?High-Quality Paint Solvent?
   • Used in high-temperature baking paints such as automotive paint, television paint, refrigerator paint, and aircraft paint to extend drying time and achieve a high-gloss surface.
   • Acts as a co-solvent in latex paints to enhance film flexibility and film-forming performance.
2. ?Printing Ink Applications?
   • Serves as a high-boiling-point solvent in screen printing inks to prevent clogging and ensure printing precision.
   • Improves ink flow and adhesion, particularly suitable for polystyrene coating printing glazes.

II. Industrial Cleaning and Surface Treatment

1. ?Cleaning Agent Formulations?
   • Used in metal and glass surface cleaning agents to effectively dissolve grease, resin residues, and flux.
   • Functions as an electronic component cleaning agent (e.g., circuit board wipes, photoresist removers).
2. ?Paint Stripping and Removal Agents?
   • Participates in paint stripper formulations to remove resin and rubber coatings.

III. Polymer Material Processing

1. ?Resin Solvent and Plasticizer?
   • Dissolves cellulose, phenolic resins, epoxy resins, and natural rubber.
   • Used as a diluent in adhesives to improve the film-forming efficiency of acrylic adhesives (addition amount should be ≤8% to avoid inhibiting curing).
2. ?Plastic and Film Production?
   • Serves as a solvent component in plastic film production.

?IV. Chemical Synthesis and Separation

1. ?Azeotropic Separation Agent?
   • Used for azeotropic separation of alcohol and ketone mixtures.
2. ?Photographic Material Solvent?
   • Acts as a stabilizer in photochemicals to ensure the stability of the development process.

V. Other Fields

• ?Pharmaceutical and Cosmetic Solvent?: Used as a pharmaceutical emulsifier or cosmetic additive (purity must be controlled).
• ?Pesticide Dispersant?: Enhances the dispersion uniformity of pesticide formulations.

? Safety and Handling Tips

?Environmental Characteristics?: Low volatility, complies with environmental standards, and is gradually replacing traditional toxic solvents.
