What is Propylene Glycol Diacetate？

Propylene Glycol Diacetate (PGDA) is a diester derived from propylene glycol and acetic acid. It is a colorless, low-volatility, and moderately polar solvent with excellent solvency power for a wide range of resins and polymers. PGDA is commonly used as a coalescing agent, film-forming aid, and environmentally friendly solvent in various coating and ink formulations. It is also widely adopted in adhesives, cleaning products, and agrochemicals due to its low toxicity and good biodegradability. With its high boiling point and slow evaporation rate, PGDA is especially suited for applications requiring extended open time.
