Propylene Glycol Diacetate

Propylene Glycol Diacetate (PGDA) is a versatile organic compound widely used in industrial applications. Its main uses can be summarized as follows:

I. Solvent Applications

1. ‌Inks and Coatings‌
   • Used as a solvent in nitrocellulose lacquers, printing inks, and fluorescent coatings to improve leveling and gloss, particularly suitable for white topcoats to prevent whitening of the film.
   • Replaces toxic solvents such as isophorone, ethylene glycol monobutyl ether (anti-whitening agent), and cyclohexanone, offering high environmental safety.
2. ‌Cleaners and Paint Strippers‌
   • Used in mechanical/electronic equipment cleaners to effectively dissolve grease and stains.
3. ‌Resin Processing‌
   • Acts as a solvent for cellulose esters, phenolic resin baking coatings, and automotive baking paints, improving processing fluidity.

II. Polymer Material Additives

1. ‌Curing Agents and Plasticizers‌
   • Used as an organic ester curing agent for casting resins and a plasticizer for cellulose acetate, enhancing material flexibility.
2. ‌Adhesives and Film-Forming Agents‌
   • Acts as a diluent in adhesives to improve bonding performance; serves as a film-forming aid in coatings to enhance adhesion and durability.
3. ‌Polyurethane Industry‌
   • Used as a diluent for waterborne polyurethane (PU) curing agents, improving film fullness and hydrophobicity.

III. Surface Treatment

• ‌Leather Brighteners‌: Used as a solvent component to impart gloss and water resistance to leather.
• ‌Electronic Flux‌: Used in soldering processes in the electronics industry.

IV. Pharmaceuticals and Daily Chemicals

1. ‌Pharmaceutical Excipients‌
   • Used as an emulsifier and transdermal enhancer in pharmaceuticals, suitable for creams, patches, etc.
2. ‌Cosmetic Additives‌
   • Used in products such as creams and shampoos to provide moisturizing properties and low irritation.

V. Environmental Characteristics

• ‌Low Toxicity and Eco-Friendliness‌: Slow volatility, good biocompatibility, complies with low VOC requirements, and gradually replaces traditional toxic solvents.

️ Physical Properties and Safety Notes

‌Note‌: Industrial applications require attention to purity (≥99%) and control of impurities such as acid value and moisture.
