Acetates & Esters, High-Purity Solvents

Neopentyl Glycol Diacetate (NPGDA)

Neopentyl Glycol Diacetate (NPGDA) 2223-82-7 / 13431-57-7

Neopentyl Glycol Diacetate (NPGDA) is a high boiling, low odor coalescing agent and solvent, primarily used in water-borne coatings. It provides excellent film formation at ambient and low temperatures, enhancing flow, leveling, and scrub resistance while offering good hydrolytic stability. This clear liquid with a mild ester odor is insoluble in water and also functions as a solvent in applications like paint removers, industrial cleaners, and textile dyeing. Furthermore, NPGDA serves as a raw material in the synthesis of organic chemicals.
