Dipropylene glycol methyl ether acetate

Dipropylene glycol methyl ether acetate is an environmentally friendly high-boiling solvent widely used in various industrial fields. Its main applications are as follows:

I. Coatings and Ink Solvent

1. ‌High-end Coatings‌
   • Used as a diluent for solvent-based coatings (such as automotive paint, aircraft paint, and appliance baking paint) to enhance coating adhesion, gloss, and wear resistance.
   • Extends drying time, prevents film whitening, and optimizes high-temperature baking processes.
2. ‌Printing Inks‌
   • Used in screen printing inks to improve fluidity and printing precision, preventing plate clogging.
   • Enhances the dispersion stability of polystyrene coating printing glazes.

II. Electronics Industry

1. ‌Cleaning and Photolithography Processes‌
   • Used as a cleaning agent, photoresist diluent, and photoresist remover in liquid crystal display (LCD) production.
   • Applied in semiconductor manufacturing for wafer backside photoresist cleaning.

III. Polymer Material Processing

1. ‌Resin Solvent‌
   • Dissolves acrylic resins, epoxy resins, cellulose, and alkyd resins to improve coating uniformity.
2. ‌Plasticizer and Adhesive‌
   • Acts as a plasticizer to enhance flexibility and processability (e.g., plastic films, pipes).
   • Used as an adhesive diluent to improve film-forming efficiency (addition amount must be controlled to ≤8%).

IV. Daily Chemicals and Pharmaceuticals

1. ‌Cosmetic Additive‌
   • Used in hair dyes, perfumes, and lipsticks for its transdermal moisturizing effect.
2. ‌Pharmaceutical Excipient‌
   • Serves as a raw material or transdermal enhancer for synthetic drugs (e.g., antibiotics, analgesics).

V. Other Industrial Applications

• ‌Cleaning Agent‌: Formulated for metal/glass surface cleaners to efficiently remove grease and resin residues.
• ‌Fuel Additive‌: Improves combustion efficiency and reduces emission pollution.
• ‌Leather Tanning Agent‌: Maintains leather softness and gloss.

️ Safety and Environmental Characteristics

‌Note‌: Industrial applications require attention to purity (≥99%) and acid value control. It has poor compatibility with isocyanate curing agents and requires the addition of catalysts.
